Using <base href=""> throws exception in tabs.js

My site uses

<base href="http://mysite.com/" />

And so my anchors for my tabs are rendered like this

<a href="/folder/page.html#one">Tab One</a>
<a href="/folder/page.html#two">Tab Two</a>

When initializing the tabs, an error is thrown:

Control.Tabs: #page.htmlone was not found on the page.

Changing line 79 of tabs.js from

link.key = link.getAttribute('href').replace(window.location.href.split('#')[0],'').split('/').last().replace(/#/,'');

to

link.key = link.getAttribute('href').replace(window.location.href.split('#')[0],'').split('#').last().replace(/#/,'');

Works for me. I'm not sure why the orig code wants to get the filename (that last split). In fact, I think this may work too:

link.key = link.getAttribute('href').replace(window.location.href.split('#')[0],'').split('#').last();

Apologies in advance if this is not thorough enough.
