title: UISearchBar linked with a UISearchDisplayController in the header of a UITableView in iOS7
body: <p>I have a <code>UISearchBar</code> linked with a <code>UISearchDisplayController</code> in the header of a <code>UITableView</code> in <code>iOS7</code>.</p>
  
  <p>I set the <code>UISearchBar</code> with the style minimal. When the <code>searchdisplaycontroller</code> shows his table it has the behavior of the picture below. The table is scrolling above the searchbar. When I switch the style of the tableview to Prominent the table scrolls under the searchbar as expected.</p>
  
  <p>Is this a bug or this behavior is expected?</p>
