Ending HTML Comments stripped out in Firefox

Hi, I have been working on a nasty problem where my programs that drive CKeditor fail on Firefox but work fine in IE. I have narrowed the issue down to this... When the file being edited ends with an html comment, that comment is removed when editing in Firefox, but not removed when editing in IE.

Here is the source HTML

<html>
<head>
<title>Test file</title>
</head>
<body>
This is the stuff in the body
</body>
</html>
<!-- here is a comment -->

And here is how that html looks in CKeditor (latest version) when viewed in the editor's source mode in IE

<html>
<head>
<title>Test file</title>
</head>
<body>
This is the stuff in the body<!-- here is a comment --></body>
</html>

Note that the editor moves the comment to within the <body> tag.

Now here how that same html looks in CKeditor when viewed in the editor's source mode in Firefox

<html>
<head>
<title>Test file</title>
</head>
<body>
This is the stuff in the body</body>
</html>

Note that the comment tag has been removed completely.

This behavior is screwing up the programs I wrote to drive the editor. Can you reproduce this behavior? Is there a way to stop the removal of ending comments? Thanks.

I have also tested this on Chrome and Safari. They work like FF does, ending HTML comments are stripped out of CKeditor. Only IE retains the ending comments.

Yes, the team is aware of this and similar bugs. A patch for IE was created a while ago, but it appears the other browsers still don't have one. Here's a link to such a dev ticket (bottom part links to similar tickets as well):

Re: Ending HTML Comments stripped out in Firefox

Because of how long these bug reports have been open, it looks like a fix a not coming soon?

To work around this issue I tried replacing the ending comments with dummy tags that I made up. Something like

<tunedin_ssi_1>something</tunedin_ssi_1>

but I find that the editor moves these tags around from where I originally positioned them in the HTML source. Is there a way to tell it to stop doing that?
