[csswg-drafts] [css-view-transitions-2] [scoped] What is the paint order of the ::v-t pseudo in relation to the scope? (#12325)

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

== [css-view-transitions-2] [scoped] What is the paint order of the ::v-t pseudo in relation to the scope? ==
This issue tracks an open question about the behavior of [Scoped View Transitions](https://github.com/WICG/view-transitions/blob/main/scoped-transitions.md). Further context appears in the document [Self-Participating Scopes](https://bit.ly/svt-sps).

**Q: What is the paint order of the ::v-t pseudo in relation to the scope?**

A child of the scope would normally be stacked with other children according to its `z-index`, but the `::view-transition` pseudo-element should probably be handled specially so that it sits on top of everything in the scope.

This is not what Chromium currently does ([crbug.com/421927605](https://crbug.com/421927605)).

(Because participants have their render output redirected, this question only matters for children that are _not_ participants and whose `z-index` is larger than that of the `::view-transition`.)
