Bug in Internet Explorer when appending object/embed-element

[arjen.vanderende@…]

I've noticed a bug in Internet Explorer 6 and higher when appending a quicktime-object. The object seems to be appended at an incorrect location, because trying to empty the element in which it is placed will yield no result. I stumbled upon this when using one of the media-plugins for Jquery. In earlier versions of Jquery (1.0.4 and earlier) the plugin works because it inserts the object with html(), which has been changed/updated since the 1.1 release to use append. Appending the object in Firefox or Safari works like a charm, so I guess it's an IE-bug only. As far as I can tell this bug has been present since the initial 1.0 release of Jquery. A testcase can be viewed at this location:  http://www.mrvulcan.nl/jquery/

The problem can be traced to how IE handles appendChild for object/embed elements. I've stripped out as much jQuery as possible to demonstrate the underlying browser bug.

var htmlized = $('<object classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" codebase="http://www.apple.com/qtactivex/qtplugin.cab#version=6,0,2,0" height="800" width="800" ID="Qtactivexplugin1"><param name="src" value="http://malsup.com/jquery/media/simpsons.mov"/><embed src="http://malsup.com/jquery/media/simpsons.mov" pluginspage="http://www.apple.com/quicktime/download/" height="800" width="800" /></object>').get(0);
document.getElementById('movie').appendChild(htmlized);

It works however if you set it with innerHTML:

var mystring = '<object classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" codebase="http://www.apple.com/qtactivex/qtplugin.cab#version=6,0,2,0" height="800" width="800" ID="Qtactivexplugin1"><param name="src" value="http://malsup.com/jquery/media/simpsons.mov"/><embed src="http://malsup.com/jquery/media/simpsons.mov" pluginspage="http://www.apple.com/quicktime/download/" height="800" width="800" /></object>';
document.getElementById('movie').innerHTML = mystring;

The output in IE using the appendChild method (very screwy):

1. The object element fills the window starting from the origin { top: 0, left: 0 }, identified as "0" in the ascii art below.

2. The descendant embed element is centered at the origin of the parent object element.

+--------|--------+        |                                |
         | OBJECT          |                                |
         +-----------------+                                |
         |                                                  |
         |                                                  |
         |                                                  |
         |                                                  |
         |                                                  |
         | WINDOW                                           |
         +--------------------------------------------------+

The same results occur with any amount of HTML wrapped around the object/embed. To fix this we would have to catch the scenario that the document fragment being appended has a a QuickTime object/embed tag in it and, if so, handle everything with innerHTML. Not a fun proposition.
