title: I can't use both "hover" and "outsideClick" triggers on Angular Bootstrap Tooltips
body: <p>I'm using Angular Bootstrap and want to have my tooltips trigger using a "hover" on desktop and "click" on mobile devices which can't hover but also have the tooltips close if you click outside the tooltip. I set it to <strong>tooltip-trigger="hover outsideClick"</strong> since "outsideClick" is now a supported trigger (<a href="https://github.com/angular-ui/bootstrap/tree/master/src/tooltip/docs">https://github.com/angular-ui/bootstrap/tree/master/src/tooltip/docs</a>), however this breaks the tooltip completely so even the hover doesn't work.</p>
  
  <pre><code>&lt;span class="glyphicon glyphicon-info-sign" tooltip-trigger="hover outsideClick" uib-tooltip="Tooltip text here"&gt;&lt;/span&gt;
  </code></pre>
  
  <p>Is there any way to make these work together?</p>
  
  <p>If I just use <strong>tooltip-trigger="hover click"</strong> it's decent, but on mobile I can only close the tooltip by clicking the item again, versus being able to click elsewhere on the page to close it.</p>
