Commented Issue: HTMLEditorExtender inner item CSS Class disappears [27299]

I know this is a very picky problem but still it exists!
Retro steps:
(you may do this directly on http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/HTMLEditorExtender/HTMLEditorExtender.aspx)
1- lets start by going into source mode and type this: Hello <b>world!</b><span class="test">This Is A Test</span>
2- switch to design mode
3- focus out of the control (by clicking anywhere else)
4- switch to source mode again and you will see your class disappear (this is not magic... it's a bug)
*This bug is valid for all browser on all versions! (unless i am mistaken but I've tested it in Chrome Firefox IE9 IE8(through IE9) and stopped there :P figured if it worked in <IE8 it was pretty much still a bug on all major browsers)

Thanks
Comments: Hi! Thank you for your report. We have fixed the issue you described, and this fix will be available in the next AJAX Control Toolkit release. Now the id and class attributes aren't deleted by default. If you want HtmlEditor to delete these attributes, enable sanitization by setting "EnableSanitization" property to true. Best regards, Fadil
