WordPress Wierd Issue; Unescaped HTML tag in Heading was the culprit

I have downloaded Internet Explorer 11 to test the browser. It is developer version but working without any issue.

The above text is crashing this web page. Left sidebar was not coming. I got this while writing this post on IE 11.

Now, I got it and you wont see the problem. Here is some awesomeness:

The error was due to <title> tag coming un-escaped from Heading of a post and Related Post plugin was showing that. Code snippet from Source code of problem page:

<div class='yarpp-related'>
<div><b class="hc">Possibly Related posts:</b></div><ul id="rpost">
