Invalid HTML causes infinite loop in IE

[Wiktor Walc]

This bug was introduced here: ​http://dev.fckeditor.net/ticket/2156

In IE, paste the following content in the source mode:

<p id="1"><strong></span></p>
<p id="2"><strong></span></p>
<p id="3"><strong></span></p>
<p id="4"><strong></span></p>
<p id="5"><strong></span></p>
<p id="6"><strong></span></p>
<p id="7"><strong></span></p>
<p id="8"><strong></span></p>
<p id="9"><strong></span></p>
<p id="10"><strong></span></p>
<p id="11"><strong></span></p>
<p id="12"><strong></span></p>
<p id="13"><strong></span></p>
<p id="14"><strong></span></p>
<p id="15"><strong></span></p>
<p id="16"><strong></span></p>
<p id="17"><strong></span></p>
<p id="18"><strong></span></p>
<p id="19"><strong></span></p>
<p id="20"><strong></span></p>
<p id="21"><strong></span></p>
<p id="22"><strong></span></p>

then switch back to wysiwyg, press source button again - IE hangs and enters an infinite loop, after a while it asks whether script execution should be stopped.

The problem is caused by FCKXHtml._RemoveXHtmlJobProperties() function in fckxhtml_ie.js.

Looks reasonable and fixed the issue for me.
