TransitionInteractiveController performs the navigationAction only depending on the swipe velocity. We want to support parameterized handling so we can start the transition only if a requirement is met before swiping.
For example if our presented UIViewController has a UITableView we want to make sure the contentOffset.y is 0 before starting a transition triggered by a Pan.regular(.fromTop).
