CSS Syntax Level 3 invalidates this test with a change proposed in [1] and accepted by the working group in [2]. All list of declarations (including the body of style rules) are parsed with the algorithm at [3] and can also contain at-rules. Even if no at-rules is supported in a given context, this affects error recovery.

(We should probably get the test fixed, though.)
