We should always finish the controller when requested, to ensure
everything is cleaned up immediately. But if touch is in progress,
we should keep input proxy enabled until touch up/cancel.
Test: swipe up to launcher and interact with it during the transition
- Swipe to recents and scroll it or dismiss the current task
- Swipe to home and open another app or swipe again on the nav bar
