I agree.  I think that autoselection should not occur while the menu
bar menus are active, even if the mouse temporarily moves out of the menus.

    If I wanted to do this, I'd have to intercept `x_activate_menubar',
    detect whether the `mouse-autoselect-window-timer' timer is active, and
    kill it.  As a consequenece autoselection would be cancelled as soon as
    the user accesses the menubar.  Rescheduling the timer seems hardly
    feasible since it would almost certainly break the behavior for users
    with a smaller delay.

I don't think that is right either.  Whenever the menu bar menus cease
to be active, autoselection should resume.  An outcome where the mouse
remains for a longg time in the upper window but the lower window remains
selected is not correct.

But it would be good to restart the delay when the menus become
inactive, so as to give the user a chance to move the mouse back to
the lower window.
