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

Different blocks have different requirements - the child rules in @keyframes use a different prelude syntax than style rules. Can't really be generic here.

There's also the question of "why?" - what does putting an entire style rule into an @supports test achieve? If it's testing selectors, we already have `selector()`; if it's testing properties, that's the original feature. There's no interaction between the two to worry about, either.
