If I had to guess, this is probably because <row> and <rows> do not implement
IsContentOfType(nsIContent::eELEMENT) for some reason.  Or it could be because
of weird parentage.

I get "description" for all the descriptions in that testcase in a current
build...  Marking worksforme.  Please reopen if this is still a problem, though.
