Maybe step 1 should say:

I think it should say:

1. If the image argument is an HTMLImageElement object in the broken state,
then throw an InvalidStateError exception, return aborted and abort these
steps.
2. If the image argument is an HTMLImageElement object that is not fully
decodable, or if the image argument is an HTMLVideoElement object whose
readyState attribute is either HAVE_NOTHING or HAVE_METADATA, then return
bad and abort these steps.
3. (original step 2, unchanged)

in order to match Firefox/IE's behavior.  (I don't know if that's the right
exception to throw.)
