Swiping back when both controllers have a UISearchController makes them both disappear.

[Garrett-Benoit]

Hello, I hope you are doing well! After some testing, I have discovered that when both the root controller and the one pushed on screen have search bars as the navigationItem.titleView and the user swipes back on screen both of the search bars in both controllers disappear, however if the user taps on the blank navigation bar it will still interact as though the search bar is visible. However, when the user taps the "< Back" button in the navigation bar instead of using the swipe anywhere feature, the search bar stays visible as it should. Cheers!
