title: Jquery AjaxSubmit + json datatype stripped HTML in IE9
body: <p>I'm doing a file upload using jquery form.js. The server side code returns a json formatted string, with one of the fields being "content". The content field has an HTML form, that I just grab and spit out on the page in a div.</p>
  
  <p>This works perfectly fine in Chrome and Firefox, but fails in IE9. IE9 strips all opening HTML tags. I've been googling all day long and tried a whole lot of things, but I can't fix it. </p>
  
  <p>Here is my Jquery code:</p>
  
  <pre><code>    $('#file_form').on("change", ".file_upload_field", function(ev) {
          ev.preventDefault();
  
          var options = {
              url: '/ajax/process',
              type: 'post',
              dataType: 'json',
              success: function(response) {
                $('#upload-confirm').show().html(response.data.content);
              }
          };
  
          $('#my-form').ajaxSubmit(options);
      });
  </code></pre>
  
  <p>Response is structed like this</p>
  
  <pre><code>{
    "success": true,
    "message": "success",
    "data": {
      "content": "&lt;form&gt;&lt;input type=\"text\" /&gt;&lt;/form&gt;"
    }
  }
  </code></pre>
