status-planned (possibly-related cause)
Some people are experiencing a problem where the auto link does not appear. This has to do with the fact that the DOM elements on which the selector is based or dynamically loaded into the DOM.
The workaround for this is to change line 683 to:
setTimeout(function() {
$('#' + divid).find('.comment-help-link').parent().append(newspan);
}, 10);
Basically this is just a minor time out before trying to add the link, which should not be noticeable.
I'm not 100% sure about the 10 milliseconds, but it works for me (Chrome Canary). If it still doesn't appear for you try 100 milliseconds or something like that.
