[csswg-drafts] Pull Request: [scroll-animations-1] Align timeline scoping closer to anchor scoping

andruud has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

== [scroll-animations-1] Align timeline scoping closer to anchor scoping ==
This implements the resolutions in #12581 and #13364, making the timeline search look upwards until it finds a matching definition, using the last defined named within a scope otherwise.

Explanations for the <dashed-ident> and 'all' values of timeline-scope are now identical with the corresponding values of anchor-scope, except that it explicitly mentions the flat tree.

Add "nice boxes" as seen from several other specs, e.g. css-anchor-position-1. (This only affects the algorithm added in this commit--apparently it's the first.)
