[csswg-drafts] [css-scroll-anchor-position-1] Working with Scroll Driven Animations (#9379)

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

== [css-scroll-anchor-position-1] Working with Scroll Driven Animations ==
The spec currently says that the anchored element position is determined as if all of the scrollers are scrolled to the top. The scrolling adjustment is then made by a snapshot scroll offset. I think this works fine for the common scrolling case.

However, with addition of scroll driven animations, a scroll offset can now affect a progress of an animation which can affect far more than just a translation. It isn't clear if the spec means that these animations should be at 0% progress because the scroll is at the top. I think it's worthwhile to call out scroll driven animations explicitly and figure out how to handle the interaction.
