My intuitive understanding is that the WM considers this frame 
fixed-size for some reason. And when mouse dragging of the top border is 
initiated, it is indeed resized by moving the top border.

And then some other piece of code somewhere sees that and thinks, hey, 
this window must be X height! And fixes the situation by resizing it 
back (but moving the bottom border). Which makes the frame move.
