[csswg-drafts] [scroll-animations-1] Entry/Exit Transitions for View Timeline effects (#7044)

fantasai has just created a new issue for https://github.com/w3c/csswg-drafts:

== [scroll-animations-1] Entry/Exit Transitions for View Timeline effects ==
There's a strong use case for wanting to animate while an element enters or exits the view, see e.g. https://github.com/w3c/csswg-drafts/issues/4912

However View Timelines as currently defined don't have the ability to bookmark the start and end of the entry or exit phase and to attach a set of animation frames to just that phase.

We could change the ability of view-timeline-fit to match the entry or exit phase, rather than the full cover or contain phase; but this would mean that many common use cases become a patchwork of separate animations on separate timelines stitched together, which is awkward.
