I don't see how that could be possible.  The problem is not (only) the
order of displaying windows, the problem is that displaying each
window many times invokes the move_it_* functions that go beyond
window boundaries, and make decisions based on that.  These decisions
end up incorrect when the text beyond the window is displayed in a
window of a different width.
