Shouldn't this have ASSERT_NOT_REACHED?

I think it would be better to do this when we reach HAVE_METADATA, or an element with "preload=metadata" may not ever notify the client even thought it found and loaded part of a valid media file.

Is HAVE_METADATA guaranteed to only fire once?  (It looks like we will never drop down below HAVE_METADATA unless the user cancels load.  So yes.)
