Also as kenneth said, Qt Gtk and Mac DRT test the flame flattening feature. Please, make sure there is no regression.

Well, if we go for it, I would also suggest to add an assert here:


That way we ensure that no one is calling setHasVerticalScrollbar() without previously calling avoidScrollbarCreation()
