title: Navigation bar with "Prefers Large Titles" and embedded PageViewController not collapsing
body: <p>I have setup a &quot;UIViewController&quot; (Embedded in &quot;UINavigationController&quot;), and the &quot;UIViewController&quot; has a &quot;ContainerView&quot; with a &quot;UIPageViewController&quot;.</p>
  <p>In the &quot;UIPageViewController&quot; are few subviews with &quot;UITableViews&quot;.</p>
  <p>The problem is now, the &quot;UINavigationBar&quot; with enabled &quot;Prefer Large Titles&quot; are not collapsing if the TableView (Embedded in ContainerView) scrolls.</p>
  <p>I think that's a problem with the &quot;UIPageViewController&quot;. The size is the same as the ContainerView.</p>
  <p>How can I fix this issue ?</p>
