[csswg-drafts] [css-contain-2] content-visibility should pause css animations in subtree (#5611)

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

== [css-contain-2] content-visibility should pause css animations in subtree ==
[content-visibility](https://drafts.csswg.org/css-contain-2/#content-visibility) property, when [skipping](https://drafts.csswg.org/css-contain-2/#skips-its-contents) its contents should also pause css animations, as if [animation-play-state: paused](https://drafts.csswg.org/css-animations/#animation-play-state) has been applied to them. 

This allows UA to skip work that would otherwise be necessary to keep the animations going and up to date.
