[csswg-drafts] [css-view-transitions-2][scoped] Allow starting a scoped view transition on a shadow root (#12953)

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

== [css-view-transitions-2][scoped] Allow starting a scoped view transition on a shadow root ==
Currently transitions can only be started on an element/document.
Starting a transition on the element as the scope, would only include same-tree descendants of that element when finding participants.
Considering adding `shadowRoot.startViewTransition`, which would pick elements and create pseudo elements inside the shadow scope.


> How does this work with Shadow DOM? If I'm manipulating multiple elements that are directly the children of a shadow root, what do I call `startViewTransition()` on?
