When a spied-upon element is destroyed, and that spy is currently active, trigger the
duScrollspy:becameInactive
event. This doesn't matter if the client code is just using the class for styling, but if it's actually making use of thebecameActive
/becameInactive
events then the client will end up in the wrong state. This also maintains symmetry withaddSpy
, which forces the handler to run (and possibly triggerbecameActive
) as soon as the spy is added.
