The expected result is that all old gestures continue till they are finished/cancelled
|
|
and the new recognizer starts creating gestures immediately at registration.
|
|
|
|
This implies that deleting of the recognizer happens only when there are no more gestures
|
|
that it created. (since gestures might have a pointer to the recognizer)
