Typo in wrap() function?

Typo in wrap() function?

I just got stuck on an exception in IE8 which is caused on the fact that I wanted to wrap some .contents() result with "<div class='anything'></div>".

Trying to debug the problem I noticed the following code in line: 3992:

    wrapMap._default = [ 1, "div<div>", "</div>" ];

Is the leading "div" a typo? I would have expected this to read:

    wrapMap._default = [ 1, "<div>", "</div>" ];
