now that you have a version of this in WPT, perhaps you should just delete this
LayoutTest (verify that the WPT test is indeed passing of course).

Oh, but we can't update the WPT test until the stupid spec IP issues are
resolved I guess :-(.  So then maybe the best choice is to have an updated copy
of the WPT test here marked as temporary until the spec issue is addressed?

Done.
