title: history.pushstate not updating title
body: <p>I am using AJAX to load main content of the page. Using <code>history.pushstate(Object:State, String:Title, String:URL)</code> - I am able to update the URL in the address bar and navigate back in the history.</p>
  
  <p>However the <code>title</code> parameter appears to have no effect. Neither does the window title change nor the title of the entries in the 'history list' (perhaps both of them are same anyway).</p>
  
  <p>What am I doing wrong?</p>
  
  <p><strong>Update</strong>: <code>title</code> param is simply ignored in chrome. <a href="http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2010-June/026827.html" rel="noreferrer">http://lists.whatwg.org/pipermail/whatwg-whatwg.org/2010-June/026827.html</a></p>
