We unshipped these a while ago and left the pref just for testing
purposes. But now all the reftests using it were conveniently migrated
to chrome:// tests, so we no longer need it.

The changes should be trivial.
The third_party changes are up for review in
https://github.com/servo/rust-cssparser/pull/277 (and of course I'll
land with a bump to 0.28 rather than the override after that gets r+'d).
The basic idea is that with this we have the actual start offset of the
rule, so we wouldn't include html comments or other invalid stuff we
discard during sanitization in bug 1680084. But that's a separate
change.

The browser currently only enables plugin behavior for Flash and our internal test plugins. This patch replaces support for those plugins with a simple fallback that shows a transparent region where the plugin would have been. It removes the file system search(es) for the plugin dynamic libraries and short-circuits the logic to determine if plugins should do something special -- all implementations now behave the same in the presence of plugin elements.
The new behavior is:
1. If the <object> or <embed> element lists a type of something other than "x-shockwave-flash" or "x-test" then the behavior is unchanged. This means that non-plugin types behave properly and unknown types (for example, typos) are also unaffected (they reduce to 0x0 elements).
2. If the <object> element has an HTML fallback in the DOM (see spec for <object> elements) then the fallback is always shown.
3. Otherwise, the element is shown as a transparent region with the size specified in attributes.

The spec text has been improved a while ago, so I think we should do
this. This keeps the current moz-focusring behavior when the pref is
disabled, but when enabled it becomes effectively an alias of
focus-visible.

In order to determine whether classes or ids are case insensitive we
need the document quirks mode. The sheet quirks mode almost always
matches, but may not match when sheets are added by privileged APIs.

Allow-list all Python code in tree for use with the black linter, and re-format all code in-tree accordingly.
To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

Otherwise on Windows, we have a ColorID::Scrollbar but not any of the other scrollbar part
colors, and the Windows-provided value for Scrollbar doesn't work well
with the default values for the other scrollbar parts that come from the
non-native theme.

Which allows to run CSS.supports in chrome/user-agent context. We should
probably add a couple more tweaks for stuff like quirks or what not (the
`ParsingMode` enum), but that seem lower priority.
I only added the one-value version of CSS.supports because it should be enough
and supporting the two value version required a bit of awkward code due to when
we parse the CSS property name right now.

This renames the internal -moz-math-script-level property in order to
prepare for full math-depth support. Currently, the property is guarded
under a disabled-by-default flag, so there should be no observable
behavior change.

This patch renames the internal -moz-math-display to math-style and
exposes it under the layout.css.math-style.enabled preference. The
initial value becomes "normal" but that does not affect the default
MathML behavior since the UA style sheet sets the math-style property
explicitly on <math> tags. WPT tests are updated to use the syntax
approved by the CSSWG.

This is mostly a band-aid, though it also serves sorta as an
optimization.
The issue here is basically bug 1393323. By re-cascading, right now we
can't come up with the right before-change style if CSSOM has mutated
the rules. We really need a better way to come up with the before-change
style, as the animation-only traversal is not really sustainable (nor
fast, for that matter...).
But this avoids crashing and prevents the regression easily, so let's do
that for now.

Per spec we shouldn't behave differently depending on how we blocked the
image/object/etc.
This may have made sense in the past when ad blockers were implemented
via nsIContentPolicy, but I think nowadays it doesn't make sense, and
showing fallback is preferred.
There's a couple extra cleanups we can do after this lands, like
removing HTMLImageElement.imageBlockingStatus and simplifying a bit that
code. But I'll do that in a separate bug.

When entering or leaving fullscreen in youtube, we spend most of the
restyle time diffing custom properties, under IndexMap::eq.
Turns out that IndexMap equality is not order-aware, and thus you
actually need to make a hashmap lookup for each entry in the map, which
is unnecessarily inefficient.
Instead, just compare the iterators.
