As per the CSSWG resolution here: https://github.com/w3c/csswg-drafts/issues/4032
Previously, any and all SVG elements used its SVG object bounding box. Now, SVG
elements that have their own CSS layout box use them. These match the following
CSS rules: `svg:root, *:not(svg|*) > svg, svg|foreignObject > svg`

Bug 1779284 - [devtools] Stop maintaining a duplicate of the target list in the debugger frontend. r=bomsy

Instead we can fully rely on TargetCommand.

This fixes duplicated calls made to top level thread actor.
This was only happening with toolbox not using the Watcher Actor.
i.e. the non-multiprocess Browser Toolbox, Browser Content Toolbox and may be worker toolboxes from about:debugging.

Per the Streams spec, other specs that want to implement custom TransformStream should use [GenericTransformStream](https://streams.spec.whatwg.org/#other-specs-ts-wrapping) mixin and store a [new TransformStream](https://streams.spec.whatwg.org/#transformstream-set-up) in a slot. This implements the latter part.

This bug solves the crash that resulted from calling `nsRange::ComparePoint()` with both NAC and non-NAC nodes.
This bug does not solve the root issue, being a range with both NAC and non-NAC content
in context of a <select> element being created in the first place.

Bug 650372 - Use the style-system format hint directly in gfx, instead of mapping to a separate internal enum. r=gfx-reviewers,aosmond,lsalzman

Now that the style system has keywords for this, we don't need to define them in gfx
but can just use the enum directly. (No functional change, just code simplification.)
