[css3-syntax] @media screen;

Hi,

In 3.5.3. At-rule-prelude mode, a semicolon pops the current rule 
unconditionally. I think it should trigger a parse error for rule-filled 
or declaration-filled at-rules, just like { does for at-rules that are 
neither rule-filled or declaration-filled.

For example, these produce the same tree per the current ED:

     @media screen;
     @media screen{}

They should not. The former is a parse error, the rule is ignored (and 
does not show up later in CSSOM.)
