If I have an area A, that encompasses another area B. I am monitoring the signals for areas entered in A.
So B enters A. My on_entry callback gets triggered.
Now A's monitoring property is turned off, and then turned on again. B is still in the same place, but I want the _onentry callback to be retriggered in this case. It does not get triggered.
Area A is an attack, and B is an enemy hitbox.
