title: Adding a prototype cell to a table view in storyboard makes navigation bar title small
body: <p>I have a View Controller which segues from a previous controller that has large titles. The navigation bar in the navigation controller has the Prefers Large Titles checkbox checked.</p>
  <p>I have added a Table View to this new view controller. Until then, the title remains large. However as soon as I add prototype cells to the table view, the navigation bar becomes small.</p>
  <p>In code I added this:</p>
  <pre><code>override func viewWillAppear(_ animated: Bool) {
      super.viewWillAppear(true)
      navigationController?.navigationBar.prefersLargeTitles = true
  }
  </code></pre>
  <p>The problem is, when the view controller comes into view, the title appears small for a second and then immediately shifts to large title.</p>
  <p>How can I fix it so that it appear large as I segue and avoid that size shift once the title becomes visible?</p>
