layoutBlockChildren uses the logic that "we don't need to repaint children if
the parent needs layout, because in that case it will do a full repaint". But
by resetting the bit in layoutBlockChildren it was invalidating this logic
since by the time layoutBlock called repaintAfterLayoutIfNeeded, the latter
couldn't tell that it needed to do a full repaint. I think I explained it in my
ChangeLog ;-) and it's covered by one of the repaint tests IIRC.
