Area: UIKit Summary: When you override `inputAccessoryView` to provide a view and also override `canBecomeFirstResponder` to return YES, the UIViewController push transition turns the screen white. See video: https://youtu.be/jYnXyajylwk Steps to Reproduce: 1. Create a UIViewController subclass. 2. Override `inputAccessoryView` to return a view (e.g. UIToolbar). 3. Override `canBecomeFirstResponder` to return YES 4. Push UIViewController through a `UINavigationController`. Expected Results: During the transition, the view of the `UIViewController` should be shown. Actual Results: During the transition, the view becomes white until the transition is over, at which point the UIViewController's view finally becomes visible.
