Re: [csswg-drafts] [css3-conditional] Should CSS.supports() accept properties which are only valid in certain rules? (#5929)

As @tabatkins explained, there are cases where a property and descriptor have the same name, but these are nonetheless separate features: this is most evident for `@font-face`. For `@page` rules they behave almost exactly like properties, but technically this distinction still exists. I've slightly clarified the spec to say it's talking about property declarations within style rules (not descriptor declarations within at-rules). Let me know if you think any additional clarifications are needed.
