It's not totally clear to me when all of these states are supposed to be set. For example, nothing in the HTMLMediaElement spec says to "set the readyState attribute to HAVE_ENOUGH_DATA". However, this will at least advance the readyState to HAVE_METADATA, which is needed for other useful attributes for debugging.
