Re: [csswg-drafts] [css-shadow-parts-1] Can class name selectors apply to a part? (#3431)

> JS set `:state()` is certainly useful, but there needs to be some sort of way to do what @AmeliaBR suggested, otherwise we may see authors re-implementing native pseudo-classes with JS, which is undesirable.
> @rniwa what if these "forwarded" selectors cannot include `:state()`? And what if they're only compound selectors? Wouldn't those two things make it easier to implement?

I don't see how. The fundamental problem is states like `:hover` implicitly affecting random other elements. That would quickly lead to O(n^2) behavior given the inherited value, etc...
