In the past, we just restyled the added/modified element and its
descendants.  This wasn't quite enough, so I added code to do
additional restyling in certain cases where necessary.  This was
done in the following bugs:
https://bugzilla.mozilla.org/show_bug.cgi?id=15608
https://bugzilla.mozilla.org/show_bug.cgi?id=401291
so the code added in those two bugs is the code that handles
reresolving style on elements other than descendants.
