[css-snappoints][css-scroll-snap] Does scroll-snap-align applies to pseudo-elements?

The spec(s) do not explicitly allow scroll-snap-align and related properties on pseudo-elements, but I see no particular difficulty in allowing them, and it seems useful.

I think they should at least work on the generated content ::before and ::after pseudos, but I'd also be in favor of making it apply to all pseudo elements. As long as something has a box, we should have all we need to make things work.

The following example may be somewhat outside of typical use cases, but it doesn't seem insane, and there's no doubt about what it would do:

.spell-check-mode {
  scroll-snap-type: proximity;

}

.spell-check-mode *::spelling-error {
  scroll-snap-align: start;
  scroll-snap-stop: always;
  scroll-snap-margin: 1em;
}
