In the future if we need to we can hook these up to telemetry (in fact it's not
hard, we just need to do that in Document::ReportUseCounters).
For now I want to start using them to record whether we might have a data URI.

No behavior change, but this is simpler. I want to reuse the use
counters mechanism to fix this bug because it's a very trivial way of
asking questions about the parsed data and we need to plumb it through
the same places.

Factor out the nsIconChannel symbolic lookup, and expose it to
nsImageRenderer to do the icon look-ups with the right CSS color.

Eventually I want to simplify a lot of how the theming code deals with
overriding border / padding, and this helps with that.
Since bug 1765076 this isn't used anywhere, so I think simplifying this
is the right trade-off. Thunderbird also doesn't use it.

Parse and serialize `view-transition-class: none | <custom-ident>+`.
This property will be used after we extend `<pt-name-selector>` to
`<pt-name-and-class-selector>` for named view transition pseudo-elements.
Will do this in Bug 1956646. Also, we will handle the class matching in
Bug 1964949.

Making it conditional properly is kind of a pain right now and not
something I should land without review. Add a test so that we don't
forget to remove this or make it properly conditional when shipping it
to content.

GTK4 paned widgets (see gtk4-demo) are only a thin line.
For now this does the windows thing as that's low-risk, which looks
basically the same as we have now for most themes.
We can make it look nicer in the future if needed.

Gtk4 doesn't use different background colors for GtkColumnView (the
replacement for the treeview), so avoid computing one.
Our computation didn't have any guarantee of matching the fieldtext
foreground color.
This matches windows too. Remove unused -moz-eventreerow while at it.

Previous behaviour where we did not do compound matching is incorrect, but the
order invalidations are added bailed us out (Which makes it fragile).
Add a way to skip this "pull-up" behaviour for indexing selectors, since
element's poisition matters.

Previously, we mapped left: anchor(left); to "Resolve anchor(left) with in
horizontal axis" - However, this doesn't work for two reasons:
1. `left: anchor(left)` and `right: anchor(left)` have to return 2 different
values to produce the identical result
2. We need side data for `left: anchor(inside)` and `right: anchor(outside)`

Fixup for D241392: restrict `selectors::parser::PseudoElement` import
to Gecko, avoiding a compiler warning for Servo.
Fixup for D246780: move `QueryFontMetricsFlags` definition out of
Gecko-specific code, since its used in common APIs.

We introduce `::-moz-snapshot-containing-block` pseudo-element to wrap
the view transition pseudo-element tree. This pseudo-element is only for
internal usage and cannot be accessed from outside.
Note that the related wpt,
`snapshot-containing-block-static.html`
`snapshot-containing-block-absolute.html`
are still failed because of Bug 1960755.
Also, add a test to check the snapshot containing block in the iframe,
and avoid hitting the issue of Bug 1960755.
There is no better way to verify that we do establish the fixed
positioning containing block, because it's unlikely to make the size of the
snapshot containing block be different from the viewport size on desktop
(note: this pseudo-element doesn't expose to the web), so I verified this
patch by changing the size of snapshot containing block manually in the UA
stylesheet, to see if it establish the fixed positioning containing block.

This makes the style system pass flags down to GetMetricsForCSSUnits to specify
whether it needs the 'ch' or 'ic' units, which may trigger downloading additional
font resources.
There should be no change in user-visible behavior, except by observing (e.g. in
the devtools network panel) what resources end up being fetched in an example
like the reporter's.
