I don't disagree, but I really I don't know.
Clearly that means almost but not exactly the same thing.
I am running a build "now" (i.e. when I left home this morning) with the bogus
change from the other bug, where I change all div forms here, with
-enable-checking, to see if it still triggers. I can also try our frontend
against 4.7.2 with -enable-checking, i.e. w/o the bogosity of changing all div
forms, and confirm there is still a problem.
