This is the not-yet-fixed block part of
https://bugzilla.mozilla.org/show_bug.cgi?id=25888 .
(The inline part is fixed.  I should probably split it into multiple
bugs at some point.)

Last time I attempted to fix this, I think I gave up around when I
got to figuring out how to do margin collapsing correctly.  I think
there was something else pretty hard about it as well, though.
