title: iOS 11 navigationItem.titleView Width Not Set
body: <p>Seeing a behavior on iOS11 with a navigationItem.titleView where the width of the titleView is not the full width of the screen.</p>
  
  <p>I have a custom view that I set as the titleView. Previous to iOS11 the view would fill the navigation bar area. But iOS 11 it is not resizing to fill the width of the screen.</p>
  
  <p>I've tried setting the frame of the view before setting titleView but no luck. I've tried to force the titleViews superview to layout constraints as well but no luck. </p>
