iframe Allowfullscreen not working in ie11 , works for youtube video not for other site src
<p>Here are two lines of HTML code:</p>

<p>My website url (doesn’t work in IE)</p>

<pre><code>&lt;iframe style="box-shadow: 10px 10px 5px #888888; margin: 20px; float: right;" mce_style="box-shadow: 10px 10px 5px #888888; margin: 20px; float: right;" src="http://www.youtube.com/embed/xDMP3i36naA" mce_src="http://www.youtube.com/embed/xDMP3i36naA" scrolling="no" frameborder="0" height="230" width="400" allowfullscreen&gt;&lt;/iframe&gt;
</code></pre>

<p>YouTube (does work in IE)</p>

<pre><code>&lt;iframe style="box-shadow: 10px 10px 5px #888888; margin: 20px; float: right;" mce_style="box-shadow: 10px 10px 5px #888888; margin: 20px; float: right;" src="http://zenarate.com/index.php?r=site/embeddVideos&amp;amp;id=NzIxOA%3D%3D" mce_src="http://zenarate.com/index.php?r=site/embeddVideos&amp;amp;id=NzIxOA%3D%3D" scrolling="no" frameborder="0" height="230" width="400" allowfullscreen&gt;&lt;/iframe&gt;
</code></pre>

<p>The YouTube video link works fine but the Mysite video link will not go to full screen in Internet Explorer 11 (although both work fine in FireFox and Chrome).</p>

<p>How can I resolve this.</p>

<p>Thanks in advance.</p>
