title: Jquery addClass fadeIn fadeOut not working in IE8
body: <p>I am modifying bootstrap carousel support for IE8. This works in chrome and FF but not IE 8, it will change with no fade in. Does anyone know why?</p>
  
  <pre><code>&lt;style&gt;
    .carousel .activerow {display: none;} 
    .carousel .row { left: 0; opacity: 1; }
    &lt;/style&gt;
  
    /*I have many rows of data in the dom
     They are not visible until'active' class 
     is added.
  
     This code is binded to a link
    */
    var activeset = $active; //contains the contents of current row
    var nextset = $next;    //contains contents of the next 
  
    $active.fadeOut('slow', function () {            
        activeset.removeClass('activerow');
        nextset.addClass('active');
        nextset.fadeIn('slow');          
  
      });
  </code></pre>
