Bug 1369941 - Provide more advice about how to write fuzzy() annotations on reftests. r=dholbert Differential Revision: https://phabricator.services.mozilla.com/D3940

Bug 1369941 - Remove ability to specify fuzzy()/fuzzy-if() in reftest manifests without ranges. r=dholbert I'm removing this no-longer-used feature because it promotes a behavior (using the default 0 minimum) that means we never see reports of unexpected passes when the bugs are fixed, and thus aren't protected from the bugs regressing again.

Bug 1484559 - Ensure that the scroll frame deregister its refresh driver observers (mAsyncScroll & mAsyncSmoothMSDScroll) before it's destroyed. r=dholbert

Bug 1469741 part 2 - Ensure scrollbar has a width even when it's not supported by the theme. r=dholbert Depends on D3578 The 16px and 8px in this patch are chosen rather arbitrary. We used to have a minimum width of 16px for scrollbar, which comes from `scrollbarbutton` rule in `xulscrollbars.css`. But that rule got removed in https://hg.mozilla.org/mozilla-central/rev/76149510c0f0 as part of bug 1475033. Differential Revision: https://phabricator.services.mozilla.com/D3579

Bug 1483808 - Make webkit device-pixel-ratio media queries a proper alias to resolution. r=dholbert According to the spec: https://compat.spec.whatwg.org/#css-media-queries-webkit-device-pixel-ratio And to the Chromium implementation: https://cs.chromium.org/chromium/src/third_party/blink/renderer/core/css/media_query_evaluator.cc?l=366&rcl=1d7328865bcf06a687aafc18ff95d55317030672 They're no different than resolution. In our implementation `resolution` does slightly different stuff. Given we still haven't shipped -webkit-device-pixel-ratio, making this match resolution looks better than the opposite.

Bug 1483972 - Allow videocontrols to initialize without style r=jaws,dholbert!,jaws! This crash happens because nsVideoFrame didn't know what to do with two children in the UA Widget Shadow Root. The two children are both videocontrols, with the first one being the lingering DOM inserted by first constructor call that throws. The subsequent appendChild of the same element caused the videocontrols to be initialized again, since the previous run didn't return a widget instance to UAWidgetsChild. The fix here removes the throw statement added in https://hg.mozilla.org/mozilla-central/rev/dca187f7c72c#l3.15 , allowing the constructor to complete. Without this statement, we will rely on assertion in the test here https://hg.mozilla.org/mozilla-central/rev/4ddca5eb06c2#l2.18 to fail on slower platforms to ensure the stylesheet is loaded synchronously. An alternative fix would be to wrap up the contructor in a try catch block from UAWidgetsChild and make sure the DOM is cleaned up when the constructor throw. That however will hide the error thrown so I decided to remove the throw statement instead. Differential Revision: https://phabricator.services.mozilla.com/D3560

Bug 1484306 Part 3 - Use nsFrameList::Split() to replace the usage of FindFirstBlock(). r=dholbert Differential Revision: https://phabricator.services.mozilla.com/D3645

Bug 1484306 Part 2 - Add nsFrameList::Split(), and use it to replace the usage of FindFirstNonBlock(). r=dholbert This API is similar to Vec::Split() in Rust. https://doc.rust-lang.org/std/vec/struct.Vec.html#method.split Differential Revision: https://phabricator.services.mozilla.com/D3644

Bug 1484306 Part 1 - Add nsFrameList::FrameLinkEnumerator::Find(). r=dholbert Use it to implement FindFirstBlock() and FindFirstNonBlock(). This is a demonstration on how Find() is used.

Bug 1431255 - Part II, Create a Shadow Root in HTMLMediaElement when enabled, skipping <xul:videocontrols> r=dholbert,smaug This prevents XBL binding from being attached, and create the Shadow Root to host controls to be created by the script. Shadow Root and the JS controls are lazily constructed when the controls attribute is set. Set nsVideoFrame as dynamic-leaf so it will ignore content child frames when the controls are XBL anonymous content, and handles child frames from controls in the Shadow DOM. The content nodes are still ignored since there is no <slot>s in our Shadow DOM. MozReview-Commit-ID: 3hk41iMa07n

Bug 1472843 - Implement justify-content:left/right/start/end, align-content:start/end, align-self:self-start/self-end for flexbox. r=dholbert This commit also removes some cases & warnings about unsupported values that have now been removed from the css alignment spec. Specifically: "justify-content:[last] baseline" and "align-self/align-content: left/right".

Bug 1478138 - micro-optimize frame property lookup; r=dholbert Once we've determined an index for the frame property, we don't need to pay the overhead of checking whether that index is in bounds for the array again on the next access. It would be nice if we could avoid that overhead for removal, too, but since there's no API for that, we'll just remove the overhead for accesses.
