It results in the region no longer having a backing control (see the 
definition of "the control represented by a region"), but why would it 
remove the region? The region might be there for other reasons, e.g. it 
might have a cursor or ID specified, or the author might be using it to 
play a sound when the user tries to click on the space where the control 
used to be drawn, to indicate to the user that the control is gone.
