Re: [csswg-drafts] [css-conditional][css-transitions-2] Add an @supports keyword for support of transition-behavior for all properties (#13387)

Right, I didn't think of that. So it could also be expressed as a new function for `@supports` that tells authors whether a specific property is animatable. So something like `@supports animatable(display)`.

If that info is generally available in engines, that's a much better and future-proof approach.
