title: Large Titles weird behavior in Split View Controller
body: <p>My app is really simple, what you can see in the GIF below is a transition between the master and detail view of a UISplitViewController. The two views have <code>prefersLargeTitles = true</code>. The master,named "Chapitres", is a UITableViewController and the detail, named "Théorie", a standard UIViewController with a UITableView inside (there is the same problem even if the two are UITableViewController).
  As you can see the title has a weird behavior, when the detail view appears, the title is small but the content has a top margin as if the title was big. Then, when a scroll is perform, the title instantly gets bigger.</p>

  <p>The setup in storyboard is like in the screenshot below with a ShowDetail relationship between the "Chapitre" View and the "Théorie" View.</p>

  <p>Does anyone knows what I'm doing wrong ?
  Thank you !</p>
