[scroll-animations-1] Are timeline names tree-scoped? #8135
Description
I initially thought "yes", but then https://drafts.csswg.org/css-scoping/#shadow-names seemed to only apply to "global names" (i.e. names created by at-rules), which is not quite the case for scroll timeline names.
There's a discussion in #7916 in relation to anchor/CQ names, which seems to expect that names (also non-"global" names) are tree-scoped by default?
Either way, it would be good to state it explicitly.

Last time we discussed it, we decided that timeline names would be scoped across the flattened tree: see minutes
Lmk if you think we should reconsider for some reason

I'm not sure what to do about this issue, it seems like it was resolved in #7047 (as mentioned by @fantasai above #8135 (comment) ) and there is a separate issue as mentioned by @bramus #8135 (comment) . Do we close this and leave it to those other issues?

This is not the same issue as #8192. That affects anonymous timeline lookups as well (
scroll()), while this does not. Not having tree-scoped timelines does not match @tabatkins' most recent thinking in #7916 in my opinion. However, if we're still sure about the #7047 decision, then I'm happy to close this issue. Tree-scoped names are painful to implement anyway.Bug 1810494 [wpt PR 37982] - [scroll-timeline] Hide support for tree-…
