This signal is emitted whenever a sequence is cancelled. This usually
happens on active touches when gtk_event_controller_reset() is called
on @gesture (manually, due to grabs...), or the individual @sequence
was claimed by parent widgets' controllers (see gtk_gesture_set_sequence_state()).
@gesture must forget everything about @sequence as a reaction to this signal.
