title: ui.boostrap accordion container width issue
body: <p><a href="http://plnkr.co/edit/bEZTM5?p=preview" rel="nofollow">THIS PLUNKER REFERS</a></p>
  
  <p>I'm having an issue using ng-Grid inside a ui.bootstrap accordion. Take a look at my Plunker to see the issue in action.</p>
  
  <p>Essentially, when placing a grid inside an accordion with the child accordion-group closed on initial page load, the grid is assigned a width of zero and does not display.</p>
  
  <p>Can anyone point me in a direction to solve this, either by adjusting CSS classes or by trapping the accordion-group events and re-rendering the grid? I've been running around in circles with this one!</p>
  
  <p>EDIT: Apologies, Plunker now public!</p>
