title: Controls show through ComboBox dropdown on Windows Phone 8.1
body: <p>I'm just getting started working with XAML using VS2013 and Windows Phone SDK 8. I've got a HubSection with a few ComboBox controls in a Grid.  When you open a ComboBox dropdown, it shows controls in the dropdown that should be behind it.</p>
  
  <p>Any suggestions on how to fix this?  Even if I can open the dropdown separately (I have another ComboBox with 13 items that will show full-screen automatically if it is opened).</p>
  
  <p>Thanks for any help.</p>
