Re: [csswg-drafts] [css-view-transitions-2] [scoped] Clarify the ::v-t box and stacking context position relative to the scope (#12324)

Putting this on the agenda with the following proposal:

* We support `view-transition-group: contain` on view transition scopes that have `view-transition-name: none`. This creates a `::view-transition-group(-ua-scoped-root)` and `::view-transition-group-children(-ua-scoped-root)` with the latter hosting the descendant participating elements. There are no styling implications (i.e. the authors can style this as usual)
* We add `view-transition-group: contain` by default on view transition scopes at the time that startViewTransition is called on it.
