title: Can't move focus from table view to adjoining button on tvOS
body: <p>I have a single ViewController which contains a Table View on the left and a few labels on the right. Navigating through the table view entries works fine (up/down). Focus is no problem there. Even the related text in the labels is updated just fine using <code>tableView:didUpdateFocusInContext</code>. </p>
  
  <p>The interface looks like this:

  <p>However, the button on the right ("Jetzt ansehen") never gets focus. When I use the debugger (as suggested in the official documentation), it doesn't include the button in the focusable area at all:</p>

  <p>I really tried to solve this using <code>UIFocusGuide</code>, but I have no real idea how to accomplish that, yet. </p>
