Before filing a bug-report I'm looking for some feedback on the following.
In Firefox 3.5 and fckeditor 2.6.5 I've put the following code in the editorwindow (in source-mode):
<p><a href="http://www.fckeditor.net/" class="deeplink">FCKeditor</a></p>
.
Now I change from source-mode to wysiwyg-mode and back to source-mode, and so on.
The result is that the code is changing to
<p><a class="deeplink" href="http://www.fckeditor.net/">FCKeditor</a></p>
and the next time it changes back to
<p><a href="http://www.fckeditor.net/" class="deeplink">FCKeditor</a></p>
