title: UI-Bootstrap - Popover/Tooltip for mobile display
body: <p>I have a problem with Bootstrap-UI Tooltip/Popover-directive in mobile displays.
  If the User clicks a button with a Tooltip, this Popover is shown correctly. But unfortunately this popup will not close if the user clicks somewhere else.</p>
  
  <p>Does everyone had the same problem and found a solution for this?</p>
  
  <p>I use the latest version (0.12.1).</p>
