helpbar is not showing in bbpress and comment form

I tested on wordpress 3.7 and wordpress 3.8 sites with default wordpress 2012 theme.

Here is a sample link: http://rahul286.rtcamp.net/forums/topic/tpscscad/

To create code blocks or other preformatted text, indent by four spaces:

This will be displayed in a monospaced font. The first four
spaces will be stripped off, but all other whitespace
will be preserved.

Markdown is turned off in code blocks:
[This is not a link](http://example.com)
To create not a block, but an inline code span, use backticks:

Here is some inline code.

And in JS Console, there is a line:

JQMIGRATE: jQuery.fn.live() is deprecated jquery-migrate.js?ver=1.2.1:41
console.trace()           jquery-migrate.js?ver=1.2.1:43

Helpbar shows correctly in backend post/page editor. Issue is only on front-end.
