This is expected.  We have to get rid of the whole resize-corner special 
case before this is properly fixed, but that was a too big change for 
24.1.  Try pulling down outside of the corner, at the bottom of the 
window, and you should not get that effect.

Yes.  If there are two or more monitors, we want to be able to resize 
into the other monitor(s).  But we don't know how the monitors are 
related to each other, so we allow resizing outside the current window. 
Unfortunately this is the same thing that allows the faulty behaviour.

This may also go away when the special case for the resize corner is 
removed.
