Re: [csswg-drafts] [css-cascade] What is a valid at-rule? Or what is an invalid at-rule? (#9175)

As far as I know, excluding rules in invalid order, there are rules with an invalid prelude (eg. `@import <invalid>;`), rules with an unexpected block (eg. `@namespace ns {}`), rules with a missing block (eg. `@media all;`), and missing mandatory declarations (eg. `syntax` in `@property`).

Also curious if there are other cases.
