Summary:
The righBarButtonItem of a UINavigationBar gets stuck in the highlightedState of the button if created with UIBarButtonItem(title:style:target:action:). It works if a customView is set for UIBarButtonItem.

Steps to Reproduce:
1. Create a UIBarButtonItem via UIBarButtonItem(title:style:target:action:)
2. Set the created button as rightBarButtonItem on a navigationBar.
3. Make the action of the barButtonItem trigger a push on the navigationController
4. Press the righBarButtonItem
5. Press the back button in the UINavigationBar

A working example is attached as playground.

Expected Results:
The rightBarButtonItem should be in normal state and look like it is enabled.

Actual Results:
The rightBarButtonItem stays in the highlighted state and looks disabled.

Version/Build:
iOS 11.2

// Present the view controller in the Live View window
let navigationController = UINavigationController(rootViewController: MyViewController())
PlaygroundPage.current.liveView = navigationController
