Can't get `Spinner` option to work (jQuery UI tabs)

Question

According to http://jqueryui.com/demos/tabs, tabs that load content via AJAX will show "Loading..." while the content loads. If you want to customize this message, you can (supposedly) set the spinner option:

$("#tabs").tabs({ spinner: "Just a sec..."});

However, I'm having these problems:

• Setting the spinner option doesn't seem to work
• Even when I don't set the spinner option, "Loading..." doesn't appear
• "Loading..." doesn't appear for me on the "Content via Ajax" demo on http://jqueryui.com/demos/tabs!

Any thoughts?

Okay, I found the answer (http://osdir.com/ml/jquery-ui/2009-04/msg00769.html) -- the contents of the tab need to be enclosed in a <span>:

<li><a href="http://url">will not work</a></li>

<li><a href="http://url"><span>WILL work</span></a></li>

Needless to say, it's pretty insane that this is:

• Not documented anywhere
• Incorrect on the example page
