Safari <select> onchange form submit broken in 1.2

Safari <select> onchange form submit broken in 1.2

In my form I have a <select> box and I want the form to automatically submit when the user selects an option.
The following code works fine in IE/FF/Safari (desktop version)
  1. <!DOCTYPE html>
  2. <html>
  3.     <head>
  4.     <link rel="stylesheet" href="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.css" />
  5.         <script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
  6.         <script src="http://code.jquery.com/mobile/1.1.1/jquery.mobile-1.1.1.min.js"></script>
  7.     </head>
  8. <body>
  9.     <div data-role="page" id="page1">
  10.       <div data-role="content">
  11.         <form id="animalform" action="notexist.html" data-ajax="false" method="POST">
  12.             <select name='animal' id='animal' onchange='doChange()'
  13.                     data-inline='true' data-native-menu='false'>
  14.                 <option>What do you prefer?</option>
  15.                 <option value='3' >Cat</option>
  16.                 <option value='4' >Dog</option>
  17.                 <option value='5' >Pony</option>
  18.                 </select>
  19.         </form>
  20.       </div>
  21.     </div>
  22.     <script type='text/javascript'>
  23.         function doChange()
  24.         {
  25.             $('#animalform').submit();
  26.         }
  27.     </script>
  28. </body>
  29. </html>
It submits to notexist.html, when you see the error you know it submitted.

When I replace the head with
  1.         <link rel="stylesheet" href="http://code.jquery.com/mobile/1.2.0-alpha.1/jquery.mobile-1.2.0-alpha.1.min.css" />
  2.         <script src="http://code.jquery.com/jquery-1.7.1.min.js"></script>
  3.         <script src="http://code.jquery.com/mobile/1.2.0-alpha.1/jquery.mobile-1.2.0-alpha.1.min.js"></script>

the form is not submitted with Safari anymore. No error or anything.
