    Bug 222657 — Media element never populates its UA shadow if it was initially created in a document without browsing context

    When input and media elements are adopted with document.adoptNode() from a foreign document (via DOMParser, for example) they lose their native shadow DOM roots and are left in a mostly broken state: <input>s lose their native UI, and <video> and <audio> elements lose their native controls.
    To reproduce, open the attached adopt-node-bug.html file in Safari and compare the correct middle column (imported node) to the incorrect right column (adopted node).
    Tested in Safari v14.0.3 (16610. on macOS v11.2.2, and mobile Safari on iOS v14.4.

    Re: Bug 1043564 — Incorrect range calculated during a 'deleteSoftLineBackward' event

    Here is another example that demonstrates the issue. It works by canceling the "beforeinput" event and applying the target range to the selection to illustrate it.
    1. Open the attached "select-target-range.html" file in Chrome
    2. Place the cursor at the end of each line and press Cmd+Delete
    3. Observe the selection, which represents the target range
    4. Not that it doesn't match the actual range of text to be removed

    Trix: A Rich Text Editor for Everyday Writing with Javan Makhmali

    Today’s guest is Javan Makhmali, who works for Basecamp and helped develop Trix. Trix is a rich text editor for the web, made purposefully simple for everyday use instead of a full layout tool. Trix is not the same as Tiny MCE, and Javan discusses some of the differences. He talks about the benefits of using Trix over other native browser features for text editing. He talks about how Trix has simplified the work at Basecamp, especially when it came to crossing platforms. Javan talks more about how Trix differs from other text editors like Google Docs and contenteditable, how to tell if Trix is functioning correctly, and how it works with Markdown.

    Top of window with "hiddenInset" title bar becomes unresponsive after exiting fullscreen electron/electron#16418

    • Output of node_modules/.bin/electron --version: v4.0.1
    • Operating System (Platform and Version): macOS 10.14.2

    Expected Behavior
    The top of the window should continue responding to clicks after exiting from fullscreen.

    Actual behavior
    The top ~40px stops responding to clicks after exiting from fullscreen.

    To Reproduce

    1. Clone and run https://github.com/javan/electron-quick-start/tree/hidden-inset-mojave
    2. Click the black bar at the top of the window. It should turn purple while the mouse is down.
    3. Enter and exit fullscreen.
    4. Click the top of the window and note that it no longer turns purple.
    $ git clone https://github.com/javan/electron-quick-start.git -b hidden-inset-mojave
    $ npm install
    $ npm start


    Additional Information
    This issue is quite similar to #14529.

    Input Events Level {1,2} basecamp/trix#580

    This PR improves the way Trix records input—particularly on mobile—by adding support for Level 2 InputEvents, which are currently implemented in Safari and Chrome, and in their companion webview implementations on iOS and Android. In all other browsers, Trix will continue to work exactly as it does today. Here's how:

    First, Trix tests for InputEvent support:

    supportsInputEvents: do ->
    typeof InputEvent isnt "undefined" and
    "inputType" of InputEvent.prototype and
    "data" of InputEvent.prototype

    Then, when a <trix-editor> initializes, its editor controller installs one of two input controllers:

    @inputController = new Trix["Level#{Trix.config.input.getLevel()}InputController"](@editorElement)
    @inputController.delegate = this
    @inputController.responder = @composition

    1. Trix.Level2InputController if input events are supported
    2. Trix.Level0InputController, which is equivalent to the current Trix.InputController, if input events are not supported

    Fixes #575
    Fixes #574
    Fixes #520
    Fixes #494
    Fixes #396
    Fixes #315
    Fixes #178

    Image galleries basecamp/trix#523

    This pull request adds support for displaying groups of images in a grid, AKA image galleries. It works by automatically grouping adjacent image attachments into blocks, and styling the block's attachment elements to form a grid. The layout is 100% CSS-based so it can easily be customized or adjusted for different viewport sizes using media queries. Out of the box, Trix supports two and three column grids controlled by just a few styles in trix.css:

    .attachment-gallery {
    display: flex;
    flex-wrap: wrap;
    position: relative;
    margin: 0;
    padding: 0;
    .attachment {
    flex: 1 0 33%;
    padding: 0 0.5em;
    max-width: 33%;
    &.attachment-gallery--4 {
    .attachment {
    flex-basis: 50%;
    max-width: 50%;

    Additional changes

    1. Attachment toolbars now include file metadata, and their markup and has been revised to align more closely with <trix-toolbar>'s.
      screen shot 2018-07-25 at 9 43 48 am

    2. Text formatting can no longer be applied to attachments because, in part, the resulting HTML would break image gallery layouts. It also had weird/inconsistent results before and could easily happen accidentally (dropping images into bold text, for example).

    3. Attachments with href attributes now render <a>s inside their <figure>s.

      <!-- BEFORE -->
      <a href="">
          <img src="">
      <!-- AFTER -->
        <a href="">

    Custom Elements v1 (and v0) basecamp/trix#516

    This pull requests adds support for Custom Elements v1, the official standardized spec recognized by all major platforms. v1 has already landed in Chrome, Safari, and Opera, and development is underway in Firefox and Microsoft Edge.

    Custom Elements v1 and v0 are conceptually identical, although they don't share much in common API-wise. For better or worse, those API differences make v1 more difficult to adopt (unless you're only targeting modern browsers and delivering ES2015+ JavaScript code).

    v1 gotchas…

    Caveat: an unpolyfillable upgrade
    There are things that current V1 makes impossible to reproduce via plain JS and the most obvious is the JS instance upgrade. In older engines, extending any DOM native class is not enough to have a proper DOM instance.


    ES5 vs ES2015
    The custom elements v1 spec is not compatible with ES5 style classes. This means ES2015 code compiled to ES5 will not work with a native implementation of Custom Elements.[0] While it's possible to force the custom elements polyfill to be used to workaround this issue (by setting (customElements.forcePolyfill = true; before loading the polyfill), you will not be using the UA's native implementation in that case.

    Since this is not ideal, we've provided an alternative: native-shim.js. Loading this shim minimally augments the native implementation to be compatible with ES5 code. We are also working on some future refinements to this approach that will improve the implementation and automatically detect if it's needed.

    [0] The spec requires that an element call the HTMLElement constructor. Typically an ES5 style class would do something like HTMLElement.call(this) to emulate super(). However, HTMLElement must be called as a constructor and not as a plain function, i.e. with Reflect.construct(HTMLElement, [], MyCEConstructor), or it will throw.


    In my testing, none of the v1 polyfills worked reliably in older versions of Safari or on older Android devices. They're also far more invasive, attempting to patch every possible means of content creation / insertion. Miss one (like Element#insertAdjacentHTML) and custom elements slip through without upgrading.

    v0 on the other hand, even though it's only officially supported in Chrome, has far better support thanks to several battle hardened, MutationObserver-based polyfills. And so, this pull requests preserves support for v0 too.

    To smooth over the v1/v0 API differences, this change introduces its own distinct naming convention for lifecycle callbacks: initialize(), connect(), disconnect() (thanks, Stimulus!), and automatically maps them to the supported custom element API.


    initialize() → connectedCallback() (once)
    connect()    → connectedCallback()
    disconnect() → disconnectedCallback()

    v0 (polyfilled if necessary):

    initialize() → createdCallback() 
    connect()    → attachedCallback()
    disconnect() → detachedCallback()

    Fixes #495

    Re: Bug 6656 — Image loading continues when IMG elements or Image JavaScript objects are removed

    Hello, another Basecamp developer here with more details.
    We use `MutationObserver` to detect when images are added to the DOM and swap their "src" attribute with a tiny placeholder image. Then we restore the original "src" as images are scrolled into the viewport. This technique is commonly referred to as “lazy loading” and is intended to avoid unnecessary network requests for images that may never be viewed.
    Due to this WebKit issue, our approach doesn’t work in Safari because the original image is always loaded.
    Additionally (this may be a separate issue), cloning <img> elements causes them to load *again* even if the cloned node is detached from the DOM. For example, running `document.body.cloneNode(true)` reloads all of its images. This affects our Turbolinks (https://github.com/turbolinks/turbolinks) library, which stores “snapshots” of pages by cloning them.
    I made a video to help illustrate the problem: https://www.youtube.com/watch?v=p6bkcjoyP1M
    In Safari (left), every image on the page is loaded initially, and then loaded again when scrolled into view. Cloning <body> loads all of its images once more.
    In Chrome (right), only the first image loads initially and the rest are canceled. Cloning <body> makes no additional network requests.
    My example application and its source code are available here: https://glitch.com/~jealous-moon

    Re: Bug 764439 — composition event should be triggered on setComposingRegion

    I’m one of the maintainers of Trix (https://github.com/basecamp/trix), a rich text editor for the web. Trix, like many modern editors, listens for events to record input, and then converts that input into an editing operation on its internal document model. This process has always been challenging on Android due to its lack of key codes on keyboard events (this ol’ issue https://bugs.chromium.org/p/chromium/issues/detail?id=118639), but we’ve managed well enough by handling composition events.
    The change that fixed this issue is a significant departure from the current behavior of composition events, and problematic in a number ways:
    1. Composition events are dispatched every time you move the cursor but aren’t typing. 
    This alone quite a stretch from from the spec’s definition: “Composition Events provide a means for inputing text in a supplementary or alternate manner than by Keyboard Events” (https://www.w3.org/TR/uievents/#events-compositionevents). These composition events while moving the cursor also have no associated keyboard or inputs events, another deviation from the spec: “During the composition session, keydown and keyup events MUST still be sent” (https://www.w3.org/TR/uievents/#events-composition-key-events).
    2. The DOM selection during compositions now varies depending on the context.
    When moving the cursor, the selection during compositionupdate is always collapsed at the cursor’s position. When typing, the selection is the expanded range around the composed characters. This means we can’t reliably determine if the input is new or if it’s replacing a range of existing content.
    Description of the attached screenshots:
    cursor-movement.png: Shows the composition events dispatched after moving the cursor from left to right four times. Note how the compositionupdate data is identical, but the DOM selection is not.
    movement-then-typing.png: Shows the events dispatched when placing the cursor before "The", "quick", and "brown", and then typing "fox " at the end. This illustrates how the selection expands while typing, and how difficult it is to distinguish input from cursor movement generally.
    These screenshots come from http://jsfiddle.net/javan/mj13jj7b/embedded/result,js/ - a small test bed I made.

    Bug 174165 — DataTransfer shouldn't contain text/html when performing Paste and Match Style

    The ClipboardData for paste events are identical when performing Paste (⌘V) and Paste and Match Style (⌥⇧⌘V). Because they're indistinguishable, it's impossible to programmatically handle pastes correctly in a rich text editor (like https://github.com/basecamp/trix, which I help maintain). There's no way to infer the desired format and pick an appropriate type.
    To reproduce, open the attached paste-inspector.html file in Safari and paste as instructed. Note that the logged paste events are identical and both contain "text/html" and "text/plain" types. Chrome and Firefox only return a "text/plain" type when performing Paste and Match Style, which I assume is correct.
    This issue is also present in previous versions of Safari.

    Steps to Reproduce:

    Expected Results:
    <x-foo contenteditable>
    Actual Results:
    <x-foo contenteditable>
    <x-foo contenteditable>
    Additional details:
    Enabling dom.webcomponents.customelements.enabled and registering the element with document.registerElement has no affect.
    The same problem is reproducible using <span contenteditable> as the containing element (instead of <x-foo contenteditable>) so I suspect Firefox treats the contained elements as invalid block children of an inline parent. Styling the container with "display:block;" doesn't help, and in either case the contenteditable element should not be duplicated.

    has_many :through relations that return the same number of records and one common record with the max updated_at will generate the same cache_key. For example:

    Above, Victor Cooper has the max updated_at (20161229150259317823). If we remove Jared Davis and add a new person who's updated_at is less than Victor's, we'll get the same cache_key:

    Extends the fix from #25546 to namespaced controllers and their templates.

    Fix digesting non-HTML templates with non-unique logical names rails/rails#25411

    This fixes a pathological-sounding-but-it-happened-to-us scenario that caused incorrect template digests for */* requests that render non-HTML (JSON, in our case) templates. The scene looks something like this:

    1. An appended view path: append_view_path(Rails.root.join("app/views/api"))
    2. Partials in this path with the same logical path as partials in app/views, but for different formats: app/views/api/todos/_todo.json.jbuilder and app/views/todos/_todo.html.erb, both "logically" known as todos/todo. Both of these partials have cache fragments.
    3. A controller action (schedules#show) with a corresponding JSON template (show.json.jbuilder) that in turn renders a collection of partials: json.todos @todos, partial: 'todos/todo', as: :todo.
    4. A client-side fetch requests to this action that doesn't set an Accept header so it defaults to */*.

    The JSON response is correctly returned, but the template digest it uses for caching is computed using the HTML templates. Altering _todo.json.jbuilder does not invalidate its cache, but altering _todo.html.erb does.

    We worked around the issue by adding an Accept: application/json header. Adding a .json format to the URL would have worked around it too.

    Here are the new tests failing without the changes to ActionView::Digestor:

    $ rake test TEST=test/template/digestor_test.rb
    Run options: --seed 2948
    # Running:

    Fix fragment_cache_key cache invalidation rails/jbuilder#341

    Jbuilder currently does not account for an app's controller-wide fragment_cache_keys when computing its cache keys.

    This change adds support, and also aligns Jbuilder's caching setup with ActionView's cache helpers and Abstract Controller's fragment caching and instrumentation.

    To test, I made a fresh app with a fragment_cache_key call that should invalidate the template's cache with every request.

    # config/environments/development.rb
    Rails.application.configure do
      config.x.counter = 0
      config.action_controller.perform_caching = true
      config.cache_store = :mem_cache_store
    # app/controllers/widgets_controller.rb
    class WidgetsController < ApplicationController
      before_action { Rails.application.config.x.counter += 1 }
      fragment_cache_key { Rails.application.config.x.counter }
      def index
    # app/views/widgets/index.json.jbuilder
    json.cache! "unwavering-key" do
      json.config_x_counter Rails.application.config.x.counter

    Note that the cache was correctly invalidated and the presence logging like you'd see when using cache in an .erb template.

    PUT and PATCH requests fail in Microsoft Edge (with native Fetch support) github/fetch#340

    This isn't an issue with your polyfill per se so feel free to close it any time. We recently noticed a number of exceptions in our app stemming from Fetch-intiated PUT requests in MS Edge that lacked a request body.

    I did some digging and found that Edge's PUT requests had Content-Length: 0 so the JSON.stringify'd data we send as the body wasn't making it to the server. I also found that PATCH requests fail entirely and are never transmitted.

    These requests succeed in every browser I could find that has native Fetch support. They also succeed in browsers that don't when using this polyfill.

    I put together small demo Rack app here: https://github.com/javan/fetch-put-patch-demo

    I'm curious if you think MS Edge is doing it right and most closely following the spec. And if not, should this polyfill step in and smooth over the inconsistency?

    Thanks for your time! ❤️

    Parse bitmap data from sbix tables prawnpdf/ttfunk#22

    I set out to find an effective way of extracting emoji images from Apple's "Apple Color Emoji.ttf" font and found that the data necessary data is in the sbix table.

    This table provides access to bitmap data in a standard graphics format (such as PNG, JPEG, TIFF).

    emoji_font = Pathname.new("/System/Library/Fonts/Apple Color Emoji.ttf")
    ttf = TTFunk::File.open(emoji_font)
    char_code = "\u{1f4a9}".codepoints.first
    glyph_id = ttf.cmap.unicode.first.code_map[char_code]
    ttf.sbix.all_bitmap_data_for(glyph_id).each do |bitmap|
      filename = "glyph-#{glyph_id}-#{bitmap.ppem}.#{bitmap.type}"
      File.write(filename, bitmap.data.read)

    Add support for Rack::ContentLength middleware rails/rails#16793

    Currently, Rails is not compatible with Rack::ContentLength because ActionDispatch::Response::RackBody instances don't respond to to_ary and, even though it's not part of the Rack spec, it's how Rack decides if a body has a knowable length. There's some discussion in rack/rack@2b3abc7, which was later reverted leading to #1160. And a little more in rack/rack@9495207.

    IMO, Rack should remove the to_ary check. This change provides immediate support and should continue to work if / when Rack does make the change.

    Fix decoding strings that contain '=?', but are not actually encoded mikel/mail#509

    I ran into an exception today when sending an email that contained "1+1=?" in the subject.

    Here's a test (not included in the commit) to simulate that failure:

    it "should allow setting the value of a field to a string that contains '?='"  do
      mail = Mail.new
      mail.charset = 'utf-8'
      mail.subject = "1+1=?"
      mail[:subject].encoded.should eq "1+1=?"
      1) mail encoding using default encoding should allow setting the value of a field to a string that contains '?='
         Failure/Error: mail[:subject].encoded.should eq "1+1=?"
           undefined method `+' for nil:NilClass
         # ./lib/mail/encodings.rb:295:in `block in collapse_adjacent_encodings'
         # ./lib/mail/encodings.rb:291:in `each'
         # ./lib/mail/encodings.rb:291:in `collapse_adjacent_encodings'
         # ./lib/mail/encodings.rb:120:in `value_decode'
         # ./lib/mail/encodings.rb:101:in `decode_encode'
         # ./lib/mail/fields/unstructured_field.rb:73:in `do_decode'
         # ./lib/mail/fields/unstructured_field.rb:55:in `decoded'
         # ./lib/mail/fields/unstructured_field.rb:122:in `fold'
         # ./lib/mail/fields/unstructured_field.rb:103:in `wrapped_value'
         # ./lib/mail/fields/unstructured_field.rb:69:in `do_encode'
         # ./lib/mail/fields/unstructured_field.rb:51:in `encoded'
         # ./lib/mail/field.rb:167:in `method_missing'
         # ./spec/mail/encoding_spec.rb:25:in `block (3 levels) in <top (required)>'

    This fixes the problem by checking more closely (with a regex) to see if the string actually is encoded before proceeding.

The end! 👋
