dialog problems with IE6 + themeroller + height

dialog problems with IE6 + themeroller + height

I'm seeing an error when I try to create a dialog that has a textarea with rows="5". It sounds like it might be similar to the error described in: <a href="http://groups.google.com/group/jquery-ui/browse_thread/thread/338490ec08f857c2"> http://groups.google.com/group/jquery-ui/browse_thread/thread/338490ec08f857c2</a>
However, the resolution there was to upgrade to 1.6 and I'm already using 1.6rc5.
Any ideas?

Test Case follows:
-------------------------------
<html>
<head>
  <script src="jquery-1.3.js"></script>
  <script src="ui/jquery.ui.all.js"></script>
  <link rel="stylesheet" href="jquery-ui-themeroller-cupertino/ui.all.css"></link>
  <script>
    $(document).ready(function(){
      $("div").dialog({autoOpen:false});
      $("a").click(function(){
          var id = $(this).attr("href"); $(id).dialog("open");
      });
    });
  </script>
</head>
<body>

dialog() with themeroller and certain form fields causes an error in IE6. Test cases (click to open): <ul>
  <li><a href="#d2">2. textarea</a>
  <li><a href="#d3">2. textarea with rows set to 5 (broken)</a>
  </ul>



<div id="d1">
  <form>
    <label>Field:</label>
    <textarea>test field</textarea>
  </form>
</div>
<div id="d2">
  <form>
    <label>Field:</label>
    <textarea rows="5">test field</textarea>
  </form>
</div>
</body>
</html>
