title: Add different style to different kendo window
body: <p>I'm using multiple window on the same page and i want to apply
  different styles on which window. I try to write a wrapper over the
  window so it can be identified in the css by id but that does not work.
  This is the source:</p>
  
  <pre><code>&lt;div class="wrapper"&gt;
       &lt;div kendo-window="InitialisingApp"&gt;
       &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>This is the result:</p>
  
  <pre><code>&lt;div class="wrapper"&gt;&lt;/div&gt;
  &lt;div class="k-widget k-window...."&gt;
      ..........................
  &lt;/div&gt;
  </code></pre>
  
  <p>Any ideas about this problem?</p>
  
  <p>Thank you! Have a nice day!</p>
