title: Display scroll in modal
body: <p>I have app using angular-bootstrap and also ionicFramework.
  Problem is in angular-bootstrap $modal element. I want it has vertical scrollbar, but in ionic.css there are style:</p>
  
  <pre><code>::-webkit-scrollbar {
  display: none;
  }
  </code></pre>
  
  <p>and because of this there is no scrollbar in modal.
  I tried solve this problem in many ways, but now I am confused.</p>
