Arguably, raising an exception is the right behavior here, given the existence of queryCommandSupported.  I would really like Gecko and WebKit making this change, and reverting it in case we actually find web content which breaks because of this (which I would personally find surprising.)  If we see a Gecko bug about this, we will definitely let you guys know about it as well.
