I can't get any icons to be shown on a modal dialog box when I try to use jQueryUI via Google Ajax API. The icons do not appear but when I click on the locations where they are supposed to be the relevant functinality works (e.g. I can resize and close the modal dialog box). Here's the problematic screenshot and my code for Jetpack:

function testJQ() {
    var doc = jetpack.tabs.focused.contentDocument;
    var win = jetpack.tabs.focused.contentWindow;
    $.get("http://ajax.googleapis.com/ajax/libs/jquery/1.4.0/jquery.min.js", function(js) {
     var script = doc.createElement("script");
     script.innerHTML = js;
     doc.getElementsByTagName('HEAD')[0].appendChild(script);
     $.get("http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js", function(js) {
        var script = doc.createElement("script");
        script.innerHTML = js;
        doc.getElementsByTagName('HEAD')[0].appendChild(script);
        $.get("http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css", function(js) {
        var style = doc.createElement("style");
        style.innerHTML = js;
        doc.getElementsByTagName('HEAD')[0].appendChild(style);
        script = doc.createElement("script");
        script.innerHTML = 'var myDialogFunc = function () {';
        script.innerHTML += '$("<div id=dialog title=\\"Basic Dialog\\"> <p>The dialog window can be moved, resized and closed with the X icon.</p></div>").appendTo("body");';
        script.innerHTML += '$("#dialog").dialog({'
        script.innerHTML += '      bgiframe: true, height: 140, modal: true';
        script.innerHTML += '  });';
        script.innerHTML += '};';       
        doc.body.appendChild(script);
    win.wrappedJSObject['myDialogFunc']();      
        });
    });
    });
}
On the other hand, in a simple html document I can use Google Ajax API, load jquery and jQueryUI and get the icons correct without any problems. Here's the screenshot and source code that works as I expect:
http://www.flickr.com/photos/64416865@N00/4303522672/
<html>
<head>
<script src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
var myDialogFunc = function () {
  $("#dialog").dialog({
  bgiframe: true, 
  height: 140, 
  modal: true
 });
};
  // Load jQuery
  google.load("jquery", "1.4.0");
  google.load("jqueryui", "1.7.2");
  google.setOnLoadCallback(function() {
    myDialogFunc();
  });
</script>
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/themes/ui-lightness/jquery-ui.css" type="text/css" media="all" />
</head>
<body>
 <div id="dialog" title="Basic Dialog"> 
  <p>The dialog window can be moved, resized and closed with the X icon.</p>
 </div>
</body>
Any ideas about why I can't get the icons in my Jetpack version?
