title: NodeFilter is undefined error when using IE Compatibility mode with Kendo UI SPA application
body: <p>I am building a Kendo UI application which is working perfectly fine in IE11. But when I add the site to be displayed in compatibility mode in IE11 i am getting an error "'NodeFilter' is undefined'. It raises this error while rendering the layout. see below code.</p>
  
  <pre><code>var appRouter = new kendo.Router({
    init: function () {
      layout.render("#application");
    }
  });
  </code></pre>
  
  <p>Error is raised in kendo.web.min.js where it tries to remove white spaces (I guess by the name). This is the line of code that is failing. </p>
  
  <pre><code>var t=document.createNodeIterator(n,NodeFilter.SHOW_TEXT,function(t){...}
  </code></pre>
  
  <p><strong>EDIT:</strong>
  <s>I am not sure where the NodeFilter is defined. I cannot find it in kendo.web.js or kendo.core.js. Please help</s> 
  Just learned that NodeFilter is a property for window object. window.NodeFilter is null when compatibility mode is enabled in IE11. But Telerik demo SPA site works fine under these settings.</p>
