Summary: UINavigationController is presented as popover. When topViewController.preferredContentSize enlarges it correctly enlarges the size. However, when topViewController.preferredContentSize shrinks it doesn’t shrink the size. I guess bug may be in UINavigationController.preferredContentSizeDidChange(forChildContentContainer:). Steps to Reproduce: 1. Launch sample app 2. Tap Pop button to present the popover. 3. Tap + button to enlarge topViewController.preferredContentSize. It works. 4. Tap - button to shrink topViewController.preferredContentSize. It doesn’t work. 5. The label displays the value of topViewController.preferredContentSize. Expected Results: UINavigationController shrinks size when topViewController.preferredContentSize shrinks. Actual Results: UINavigationController doesn't shrink size when topViewController.preferredContentSize shrinks Code: https://cloudup.com/iHBzOfMODIT
