[struts2] tabbedpanel bug? Remote content retrieved 2/3 times

Using Struts 2.0.11, the following markup causes goodbyeWorld's execute
method to be called twice:

<sx:tabbedpanel id="tabContainer" > 

   <s:url action="goodbyeWorld" id="url"/>
   <sx:div label="Tab 1" href="%{#url}">Remote Tab</sx:div>   

   <sx:div label="Tab 2">Local Tab</sx:div> 
</sx:tabbedpanel>

When the remote content follows the local content (Tab 1 is placed after
Tab 2), it's called just once.

Switch out the libraries and change the tags accordingly to use 2.1.2
syntax, and I think you'll find that remote content on tab 1 calls the
action 3 times.  Remote content on tab 2 is called twice.
