Actually, in playing around with this a bit, I found that the extra
invalidation isn't always the size of the menu -- sometimes it is
much larger! I haven't yet figured out what causes the larger
invalidation, but can trigger it by having a Transcript window in the
upper right of the screen, selecting some text in it, then opening a
World menu.
