Spacers being added after tables using Firefox 3.6.15

[Matt Hartman]

Using Firefox 3.6.15 if I edit a table of the following configuration:

<table align="center" border="0" cellpadding="4" cellspacing="0" width="500">
	<tbody>
		<tr bgcolor="#ffffff">
			<td nowrap="nowrap" style="font-family: Tahoma,Arial,Helvetica,sans-serif; font-size: 11px;" width="30%">
				<span style="font-family: Arial;"><strong>EMI Item #</strong></span></td>
			<td style="font-family: Tahoma,Arial,Helvetica,sans-serif; font-size: 11px;" width="1%">
				&nbsp;</td>
			<td style="font-family: Tahoma,Arial,Helvetica,sans-serif; font-size: 11px;" width="69%">
				<span style="font-family: Arial;">EMI-48100</span></td>
		</tr>
		<tr bgcolor="#f2f2f2">

ckeditor inserts spacer tags after the table each time the code view is toggled, or on loading on the editor. Each time the code view is toggled more tags are added.

<p>
	<spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1">
	<p>
		<spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1"></spacer></spacer></p>
	<spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1">
	<p>
		<spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1"> </spacer></spacer></p>
	<spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1"><spacer height="1" type="block" width="1">
	<p>
		&nbsp;</p>
	</spacer></spacer></spacer></spacer></spacer></spacer></spacer></spacer></p>

I can only reproduce this in Firefox, and it does not happen with every table. I think is has something to do with the number of rows. If I remove rows I can get it to stop. Also, if I remove the empty column it will not add the spacers at the bottom.

This can be duplicated in the Demo by pasting the code and toggling the Code View.

WFM on latest build, could you provide a sample page for reproducing?

[Jakub Ś]

Steps to reproduce:

1. Open replacebycode sample
2. Paste the table in source mode
3. Switch to WYSIWYG
4. Open "Table Properties" dialog and close it by clicking ok.
5. Now toggle few times between source and WYSIWYG

You will see that spacer tags are added at the bottom of source code.

This is true for Firefox 3.6 on Win XP and Win7.

WFM with FF4/Win7.

Checked with latest CKEditor. Still occurs.

Have you followed my steps? I have managed to reproduce in the first try (Please see attachment).

No longer reproducible in latest CKEditor 3.6.4.
