title: Automatic scroll to top doesn't work in UITableView
body: <p>usually when tapping the top of the screen the tableview scrolls all the way to the top. For some reason this doesn't work in one of my view controllers.</p>
  
  <p>The hirarchy is as follows:</p>
  
  <p>UIView<br>
  -> WebView<br>
  -> TableView<br>
  ----->SearchBar<br>
  SearchDisplayController.</p>
  
  <p>I think I have everything hooked up correctly (datasource, delegate, ...). I have a similar view controller where everything works. The only difference seems to be WebView, which is missing in the view controller where the tap-and-scroll-to-top works...</p>
  
  <p>Any ideas?</p>
  
  <p>Best regards,
  Sascha</p>
