The "has been exposed to CSSOM" thing is a much weaker test, which was meant to
stand for "has been modified or might be modified". We don't care about the

We need to ensure we have a unique inner so that ruleLists and such have the
right pointer identity (we could do better, really, but it's harder).
But as long as the CSSOM hasn't modified them there should be no reason not to
use the cache. We can do a deep clone synchronously instead of refetching /
reparsing.
This is important because, as of right now, just using the inspector makes the
stylesheets unique, which is unfortunate.
We'll still have the modified rule bit for sheets with @import, because our
notification system for @import is silly, and on parents of imported sheets.
Fixing those are future improvements, but I see no reason not to land this.

The height used at the time is the height for vh units when the toolbar height

Pending invalidation work:
* Making exportparts work right on the snapshots.
* Invalidating parts from descendant hosts.
They're not very hard but I need to think how to best implement it:
* Maybe get rid of ShadowRoot::mParts and just walk DOM descendants in the
Shadow DOM.
* Maybe implement a ElementHasExportPartsAttr much like HasPartAttr and use
that to keep the list of elements.
* Maybe invalidate :host and ::part() together in here[1]
* Maybe something else.

This adds two AUTO_PROFILER_LABEL_DYNAMIC_... macros and updates select
usages of the old macros to use the new ones. These new macros cause
the dynamic string of the label to be included in BHR stacks.
We don't want to do this all of the time, as in many cases we may not
be interested enough in the dynamic string or it may be sensitive
information, but it is rather important information for certain cases.
This uses the same buffer that we use for the strings for JS frames,
and if we fail to fit into that buffer we just append the raw label.

Per the spec, if multiple track sizes are given, the pattern is repeated as
necessary to find the size of the implicit tracks:
1. The first implicit grid track after the explicit grid receives the first
specified size, and so on forwards.
2. The last implicit grid track before the explicit grid receives the last
specified size, and so on backwards.
We use a positive index of the auto track sizes for (1) and a negative index
for (2), so we can apply the correct specified implicit size.

The existing code wasn't sound, as CSSOM objects also needed to go away before
the shared memory goes away (as they keep references to them).
This is sound assuming no presence of reference cycles introduced by CSSOM.
We may want to live with this and rely on chrome code not writing cycles like
this with UA stylesheet DOM objects.
We could explicitly drop all potentially-static objects... That seems pretty
error prone though.
Or we could also just leak the shared memory buffer, is there any reason why we

In most cases, we run an animation on an object by changing its
offset-distance/offset-rotate, but keep its offset-path the same.
Building and flattening the path is sometime expensive, especially for
large path, so caching it makes sense to us and have a significant
performance improvement. This is for the main thread motion path
animations.
Note: Even though we support compositor animations for motion path,
nsIFrame::GetTransformMatrix() is still called during the animations for
other usages, so we may still build the gfx::Path on the main thread
without this patch, so this improvement becomes necessary for most cases.

For regular elements, whenever -moz-appearance is used, the CSS background is
ignored. Root elements were behaving specially, and the background color also
needed to be adjusted.
For example, for Windows 7, we have the following CSS rule;
```
:root {
background-color: transparent;
-moz-appearance: -moz-win-borderless-glass;
}
```
This change makes the root element more consistent with other elements, so the
extra `background-color: transparent` declaration is no longer necessary.
This change does not let content documents opt out of forced opaqueness:
Root content documents still get an opaque background color from an existing
check further down in this method.

This static method is assumed to have the same signature as the type's constructor,
and so we must have an implementation of ComputePerFrameKey for each constructor
a display item provides that is called by MakeDisplayItem. Notably this excludes
the MakeClone constructor for a lot of items.
There is a default varargs implementation on nsDisplayItem which everyone
inherits by default, so types which previously didn't overload this method
still don't need to.
Providing an implementation of ComputePerFrameKey on some display item type
shadows the varargs implementation, so one doesn't need to worry about overloading
one constructor but forgetting about another -- if you do, the compiler will only
see the overload and complain that the signature doesn't match.
One slightly annoying result of this is that display items which previously
inherited an overloaded implementation from a superclass now must provide
their own manual implementations. Although as far as I could tell, all of
those cases had a trivial implementation of key=0 (the super class supported
custom keys but the subclasses didn't make use of it).
In those cases I just hardcoded key=0, but it's possible that it would be
better to call into the superclass' implementation to be more robust to changes.

The glyph pixel space in which we rasterized glyphs differed from how we
rendered the rasterized glyphs in the shader. They need to be in
agreement because the glyph subpixel offset selected during

Additionally, during animations, we now snap the reference frame
relative offset ignoring the impact of any animated transforms. This

Some crashtests call window.location.reload one or more times. Each time the test document loads we call OnDocumentLoad, and each call of that function can lead to a RecordResult call, either directly or indirectly through WaitForTestEnd and its MakeProgress state machine.
Although the error when this happens ("program error managing timeouts") is confusing I found a couple intermittent instances of this happening in our bugzilla.
However with the fission changes to the reftest harness (which in general make things more async) this is much more common because we keep the tests alive longer before tearing down the test page, giving it more of a chance to happen.
To fix it we pass around the top level test url so it can make its way to RecordResult. This means we can ignore RecordResult calls for previous tests, and ignore the second or more RecordResult call for the current test. We reset the count when we start a new test.

Currently, "input" event is fired when the `AutoScriptBlocker` in `SetValue()`
is deleted. So, for keeping same behavior, the post processing after calling
`TextEditor` methods should be done before editor dispatches "input" event.
Fortunately, `TextInputListener::OnEditActionHandled()` is a good chance to
do that. Therefore, this patch makes it notify `TextControlState` and
`AutoTextControlHandlingState`.
Note that ideally, each method of `TextEditor` should return
`NS_ERROR_OUT_OF_MEMORY` coming from
`AutoTextControlHandlingState::OnEditActionHandled()`. However, it requires
a lot of changes in editor classes, and the case is really rare since editor
does not use fallible allocation. Therefore, it must be okay to crash in
editor if `OnEditActionHandled()` returns `NS_ERROR_OUT_OF_MEMORY`.

Previously, WR needed to update and track dependencies for all
allocated picture cache tiles in the virtual display port. This
means doing extra CPU work (dependency updates) and in some cases,
extra GPU work (larger off-screen child surfaces) than are strictly
required.
With this patch, each tile determines if it is currently visible in
pre_update. If the tile isn't visible, we skip doing dependency
updates until it is on screen again. More importantly, this is
used to reduce the world culling rect for primitive preparation,
which also means large child surfaces only require allocations
large enough to enclose the visible tiles, rather than the
display port.

This is the main patch to fix bug 1526268.
It is wrong to use the cached rects relative to the root
frame (ViewportFrame) to detect whether AccessibleCaret's position is
changed or not, because it doesn't account the root scroll frame's
scroll offset.
The effect is that we always produce "PositionChangedResult::Changed"
when scrolling on position:static elements, but
"PositionChangedResult::NotChanged" on position:fixed elements.
This patch fixes this by using the rect relative to custom content
container, which is the actually rect to set caret's position, to check
whether the position is changed or not.
Note that even with this patch, the caret on "position:fixed" element is
still jumpy during scrolling due to APZ. Part 3 will fixed this.
