We hook the rule into cascade data, and so we can look it up by timeline
name. Now we only use StyleScrollDirection from @scroll-timeline rule.
`source` and `scroll-offsets` are skipped now and use the default values
instead because I'm pretty sure the syntax will be changed in Bug 1733260,
and `scroll-offsets` may be obsolete because the spec proposal intents to
make it be always 0% ~ 100%.
Also, add some reftests for the default `source` and `scroll-offsets`,
and different `orientation`s.
Besides, we disable at-scroll-timeline-start-end.html in Gecko because
we don't support start/end descriptors, and there are too many
intermittents in it.

To do this, we always draw the native titlebar behind the toolbox, and
then make the toolbox adapt to it by using the titlebar radius. This
makes us preserve the shadow properly.
On Wayland we'd double-draw the shadow (see bug 1509931 comment 4) so
this fixes it by trimming it as well using border-radius.

This is based off work by smurfd. But this patch doesn't support buttons
both at the left and right, which simplifies a lot the implementation.
Also, clean-up the existing env variables while at it.

This was a subtle behavior change in bug 1739464. The early-return here:
https://hg.mozilla.org/mozilla-central/rev/2fb74c67b0c5#l11.40
Meant we also bailed out from user font prioritization for system fonts.
It's unclear whether that's really the best behavior but since the
intention of the regressing patch was not to change behavior, preserving
the old behavior seems better.

We allow animating pseudo-elements like ::-moz-progress-bar (and we
treat them like regular elements).
Ideally we should store animations for these in the parent element as
well, so they survive reframes and such. But treating them as regular
elements right now means that we do animate them, but we never update
animations for them correctly because wrapper.rs assumed them to be
non-animatable.
Since it seems reasonable to keep allowing the animations to happen,
let's just correct the update code and add a test.

.fallback is always the default font for the lang group unless we're a
system font (in which case it's "none").
The only reason we need that is because we need to react to
language changes (which affect the initial font).
Simplify the model a bit doing the language lookup in gfxTextRun (this
should avoid allocating a few nsStyleFont structs too.

This seems like more sensible behavior. We have another use of
only_generic(), but that affects font sizing and other browsers agree
with us there:
<div style="font-family: monospace">Should be 13px</div>
<div style="font-family: something, monospace">Should be 16px</div>
So not touching that one.

Apparently using transparent borders and outlines is a common
accessibility technique to make those visible in HCM.
Bug 1740924 comment 9 seemed to indicate we were the only browser
rendering those browsers, but I just confirmed that Edge at least does
show them.
Keep respecting system colors as that's per spec.

In some platforms (like macOS, windows dark mode, android, and some gtk
themes) the foreground selection color might be `currentcolor`, and that
doesn't generally guarantee enough contrast with the attention
background.
Remove HeadlessLookAndFeelGTK's handling of this color since it's
useless (always overridden by prefs in all.js)

Behind a pref for now. Given these selectors do nothing on non-chrome
documents (they just don't match) it seems worth trying.
A cursory search seems to indicate they're not used for UA detection or
something like that (or at least I haven't found such an usage).

Use the same document state mechanism we have for :moz-locale-dir. Also,
simplify the setup of the later to be the same as :dir(), allowing the
matching code to be less repetitive.
This should fix some flakiness in chrome mochitests, but we have no existing
tests for these pseudo-classes more generally and since they're just
chrome-only I'm not super-excited about adding more.

This I noticed while working on the following patches. Shouldn't have
any behavior change: the behavior does in fact match the element state
flag semantics correctly if we do this. We did split the dir flags into
two element bits a while ago.
:not(:dir()) still behaves correctly of course, and we have tests for that.

For now, use IntoIterator to figure the right type to add the bound.
If we need this on types that are iterable but don't provide

The code introduced in the preceding patch deals with currentColor correctly,
