title: No scrollbar appears in container with overflow auto (IE10, Windows Phone 8)
body: <p>I have a container (let's say a <code>div</code>) with <code>overflow: auto</code>. </p>
  
  <p>The elements in it are scrolled exactly as expected, but the typical touch scrollbar doesn't appear. </p>
  
  <p>I tried to set <code>-ms-overflow-style: auto</code> explicitly, but nothing changed.</p>
