I think I've found the problem: basep->shown_alloc isn't always correct.
It is normally set in snapped_widget_size_allocate().

However basep_widget_do_hiding() calls gtk_widget_queue_resize(), but if you
move the mouse quick enough snapped_enter_notify() will be called first which
will call snapped_widget_pop_up() and basep->shown_alloc will be incorrect.

A quick fix is to set basep->shown_alloc as the window is moved/resized in
basep_widget_do_hiding():

That seems to work, but I don't know much about the panel code so it may
not be a good idea.
