No it doesn't.  The reason you can't select an element based on 
properties, which has already been given by Hixie [1] in this thread, is 
because:
   "The cascade happens before layout. You don't know an element's
    display type at the time you are doing selector matching."

Circular references is *not* the core of the problem, it's just an issue 
that would result *if* it were possible, which it's not.
