1970954 - Make view-transition-name and view-transition-class be tree-scoped names

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, task)

Description

[Boris Chiou [:boris]]

Per spec:
https://drafts.csswg.org/css-view-transitions-1/#view-transition-name-prop, and
https://drafts.csswg.org/css-view-transitions-2/#view-transition-class-prop,
view-transition-name and view-transition-class are tree-scoped names. That means we cannot use them if we specify them in the shadow trees but the usage of the class (in the selectors) of the named view transition pseudo-elements are in the top document.

The test: shadow-part-with-class-inside-shadow.html and the comment in the code.
