Why wrapAll() copy javascript code?
<p>i have a javascript code and you can see its jsfiddle <a href="http://jsfiddle.net/XwQnp/" rel="nofollow">here</a>.</p>

<p>when wrap all .inner elements with new div, it seems jquery copy javascript code (so you can see two alert when run).
is this a normal behaviour of <code>wrapAll()</code> or this is a bug?</p>
