jquery .on() event argument does not work in Firefox
<p>Kindly see this fiddle :</p>

<p><a href="http://jsfiddle.net/e9uwA/1/" rel="nofollow">http://jsfiddle.net/e9uwA/1/</a></p>

<p>What's supposed to happen here is that the smaller box should fadeout via css transition, then ontransitionend, adjust the height of the bigger box. It works fine in Chrome, Opera but it doesn't work in Firefox.</p>

<p>I think it has something to do with the second argument <code>event</code> on the .on() method of jQuery. If that isn't allowed, are there any other alternatives?</p>

<p>Thank you!</p>

<p>Oh and disregard the comments written in the fiddle :)</p>
