Re: [csswg-drafts] [css-conditional-4] Feature detection for descriptors (#2463)

It's syntactically valid in either case, we would just invalidate the rule as a whole if `syntax` wasn't a compatible value. So that would resolve to true.  (We don't, and can't, make declaration parsing validity dependent on other declarations, not least because the relevant "other declaration" might come *after* the one in question.)
