title: HTML code set as src in iframe not showing in IE 11
body: <pre><code>&lt;html&gt;
  &lt;head&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;iframe id='smartPartFrame' src='data:text/html;charset=utf-8,&lt;h1&gt;inteGREAT&lt;/h1&gt;' scrolling='no' width='1000px' height='70px'&gt;&lt;/iframe&gt;
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>The above html code used to show h1 in iframe. Chrome, Firefox, Edge working fine. IE 11 is showing the error: the page cannot be displayed. I wants to set html directly in src not file path.</p>
