title: window.parent jQuery selector not working in IE8
body: <p>This code below works fine</p>
  
  <pre><code>$('html').bind('mousewheel', function(event, delta) {
      window.parent.scrollBy(-120 * delta,0);
      return false;
  });
  </code></pre>
  
  <p>but this one doesn't, can anyone tell me why. I'd love to know.</p>
  
  <pre><code>$(window.parent).bind('mousewheel', function(event, delta) {
      window.parent.scrollBy(-120 * delta,0);
      return false;
  });
  </code></pre>
  
  <p>I'd like to clarify that the <code>window</code> selector doesn't work in this case either.</p>
