Disable app switch drop behaviour

This behaviour causes InputDispatcher to drop input events, potentially
leading to incorrect input event streams inside the dispatcher.

This later causes a crash.

This behaviour is no longer needed, so we should remove it.

In the future, all of the related code should be deleted, as well.
