I think that's right. It appears to close the form immediately, and also
makes it display: none (otherwise CSS anonymous table boxes would be
generated all over the place). Then it leaves the form contents where
they are for the purposes of layout, but for the purposes of submitting
them, associates them with something like "the most recently-seen
buggered-up form".
