How do I center a horizontal control group in the footer - changed in jqm 1.1.1?

This used to work to center the controlgroup in 1.1.0, but now it seems like it doesn't in 1.1.1.

<div data-theme="a" data-role="footer" style="text-align:center;">
   <div data-role="controlgroup" data-type="horizontal" data-mini="true">
      <a href="foo" data-role="button">link1</a>
      <a href="boo" data-role="button">link2</a>
   </div>
   <div class="copy">&copy; 2012 bigco</div>
</div>
