[css-cascade-6] Disallow pseudo-elements in @scope's prelude #7382
Description
I think we should make it a parse error to use pseudo-element selectors in @scope's prelude (like we already do for e.g. :is/:where). It's a significant engineering effort to support properly, and it doesn't seem very useful. You could reference the pseudo-scoping-root itself with :scope, but not much else.
We should disallow it, at least until there is a point in allowing it.

Yeah this restriction makes sense.

I agree this makes sense. Could we consider that an 'obvious bugfix', or should we bring it up for (maybe async) resolution?

Obvious bugfix, imo.
