Is that really a problem, given that there are unlikely to be any
other windows near the modeline?
Well, there's the window immediately below the one whose modeline is
being dragged. If the code is able to move the modeline quickly enough,
the mouse won't end up over that other window, but relying on that in
the modeline code is going to make for brittle code. If you
click-and-hold over the modeline, then jerk the mouse down, it shouldn't
be hard to get the mouse over that other window. And I suppose that if
you have multiple small windows (a few lines each), you could even end
up with the mouse over a window that isn't even adjacent to the original
one. Bleah.
