title: Angular IE8 $index issue
body: <p>I have built a repeater that makes a couple of elements and puts them on top of each other.</p>
  
  <p>In modern browsers this works just like i expected, but in IE8 it's buggy and doesn't parse the style part (I think the content of the style attribute is invalid and that's why it doesn't show).</p>
  
  <p>It regards the following element:</p>
  
  <pre><code>&lt;div class="leaf" ng-repeat="j in getNumber(number2) track by $index" 
      style="bottom: [[$index * 3 + 20]]px"&gt;&lt;/div&gt;
  </code></pre>
  
  <p>Did anyone run into the same problem and has a proper fix for this or another way to do this.</p>
