Summary [CSS selectors] :is() / :where() should not allow pseudo-elements at parse-time

https://drafts.csswg.org/selectors/#matches: > Pseudo-elements cannot be represented by the matches-any pseudo-class; they are not valid within :is(). That seems to me like :is(foo::before) should be invalid at parse-time. Instead webkit parses it, but never matches it.
