[csswg-drafts] [css-animations-2] CSS animations on shadow parts (#4716)

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

== [css-animations-2] CSS animations on shadow parts ==
`::part()` selectors expose sets of elements in a shadow tree as through a pseudo-element selector on its host. If animation properties are set this way there is some undefined behavior.

Which tree is the @keyframes rule resolved on? Is it the shadow tree of the element or is it the host's tree.

Is the owning element the element in the shadow tree or is it the host? This effects which tree it appears in the `getAnimations()` results for.
