I think the embedding error condition should be noted somewhere in the

It probably should generate an error, yes. My patch simply ignores the
situtation.
but break the normal cases, which is not acceptable, nice try ;-)
Proper patch, reusing ctxt-depth which is not used in the HTML parser
yet to count the number of times an opening tag has been ignored, and
reused to drop the closing tags. Of course extra or missing ending tags
are still possible, but at this point one can only do heuristics. Works
properly for me, will commit soonish unless i hear a good reason against it
in the meantime:
