Re: [csswg-drafts] [css-conditional-4] selector() feature query function for selector support

Should namespace prefixes in the selector be checked against the prefixes declared in the style sheet it's used in, or should all prefixes be allowed, since we're really just checking for syntactic correctness of selectors that the browser understands?  And if we should be checking them against the declared prefixes, should any namespace prefix usage in a `CSS.supports("selector(...)")` call evaluate to false?
