title: IE8 Crash on getStyle background-position
body: <p>I've found a strange bug in Internet Explorer 8. Maybe someone can help me move around it.</p>
  
  <p>When I try to grab the background position of an element, using <code>background-position-x</code> all versions of Internet Explorer work as excepted except for <strong>IE8 that crashes</strong>.</p>
  
  <p>When I run <code>el.getStyle('background-position')</code> all browsers give me the correct values except from IE (6, 7 and 8) that return <code>undefined</code>.</p>
  
  <p>I therefore use <code>el.getStyle('background-position-x')</code> for all IE versions.</p>
  
  <p>IE8, however, crashes on the above code.</p>
  
  <p>Anyone had similar problems?</p>
