I remember discussing this with Johannes, and I think he had some reason
that he was reluctant to check for the title attr there...? I hope he
remembers because I can't seem to find record of it.

BTW, strictly speaking, we shouldn't be calling Html_parse_common_attrs()
for every element because I believe there were a few that don't have
%coreattrs under ATTLIST in the spec.
