[IE] XHTML namespace support broken

[Garret Wilson]

I have the following content:

<p xmlns="​http://www.w3.org/1999/xhtml">this is interesting</p>

On Firefox 3 this shows in the source as:

<p>this is interesting</p>

So FCKeditor has stripped out the xmlns declaration. OK. But then I create an editor on IE7 with the same comment. The source shows:

<p xmlns="​http://www.w3.org/1999/xhtml">this is interesting</p>

I then add the <em> tag around "is". This results in:

<p xmlns="​http://www.w3.org/1999/xhtml">this <em xmlns="">is</em> interesting</p>

This breaks my content. It won't even show up in the browser, as FCKeditor has taken <em> out of the XHTML namespace.

Confirmed using FCKeditor 2.6.3 beta and the latest SVN version in IE7. Works OK with FF.

It fails in FCKeditor, but it works correctly in CKEditor.
