Re: [csswg-drafts] [css-view-transitions-2]: Nested ::view-transition-group should have a container pseudo. (#11926)

I had a chat with @bramus about this this morning.

Having the  `::view-transition-nested-groups` be sized to the content box does seem painful for devs, where they'd have to recreate a bunch of sizing stuff.

The idea @bramus attributed to @flackr seemed great to me, where the `::view-transition-nested-groups` where the border size of the parent is captured, and assigned as a transparent border to the `::view-transition-nested-groups`. I know there were complexities around the layered capture, but do we hit them in this simple case?

Unless I'm mistaken, having the things inside `::view-transition-nested-groups` be in the padding box space of the parent seems consistent with scoped view transitions. My assumption is that if you call `el.startViewTransition(…)`, the root `::view-transition` will be size `inset: 0` within `el`, meaning it's the size of `el`'s padding box.
