title: css3 transform reverts position: fixed
body: <p>When using a css3 <code>transform()</code>, <code>position: fixed</code> does not apply. I made a fully working jsFiddle showing the issue: <a href="http://jsfiddle.net/SR5ka/" rel="noreferrer">http://jsfiddle.net/SR5ka/</a></p>
  
  <p>First scroll down, notice the left-hand sidebar stays fixed. Now, click <code>expand</code>, and scroll down, notice the left-hand sidebar is now <strong>not</strong> fixed.</p>
  
  <p>Any idea if there is a native css fix for this?</p>
