[csswg-drafts] Usage of `activeViewTransition` for inbound cross-document transition (#12655)

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

== Usage of `activeViewTransition` for inbound cross-document transition ==
In #12407 we've resolved on having `activeViewTransition` reflect the "active view transition" concept.
However, this might be a bit ambiguous when calling `document.activeViewTransition` before the page have been revealed in an inbound cross-document view transition. There is a pending inbound cross-document view transition, but it is not the "active view transition" until the first render opportunity. See  https://drafts.csswg.org/css-view-transitions-2/#resolve-inbound-cross-document-view-transition 

As per resolution, `document.activeViewTransition` would return null in this case. Perhaps it should resolve the view transition and return it? It would be useful for authors who want to skip/react to the view transition without having to wait for the `pagereveal` event.
