Is supportsCSS() even meant to take quirks mode into account?  If so, 
then I'd think that calling window.supportsCSS() would use the quirks 
mode flag of that window's document.  I don't think it's necessary to 
support quirks mode dependent behaviour of supportsCSS() based on 
arbitrary documents created with createDocument() or XHR.

But anyway, I'm not sure there's much value in having supportsCSS() -- 
or @supports -- honours quirks mode at all.

Gecko does by accident, incidentally:
