Well, IIRC there was something in some of the msword file formats where
a negative height for something specifies that its a exact height,
which a positive height specifies that its a minimum height (or the
other way around)

I imagine that this is a temporary thing, the initial size of the
containing panel is small/meaningless until its fully populated and
then its sized to something meaningful and redrawn properly.

If you're just looking for suspicious things, then there's no harm in
just fixing that up locally so you can continue, but I wouldn't commit
the temp hackery to master unless there is some obviously wrong thing
detected.
