Bug suspected

Hello,

I was looking for the descendant "child-2" of "root-node" and failed to find it.

    <div id="root-node">
        <span id="child-1"></span>
        <input type=text id="child-2" />
    </div>

I suspect a bug on line 101: I did not took the time to understand all the logic but '_Current' will never change its value and its seems more logical to check for the value of 'node'.

Regards,
