IE: Unspecified error thrown when we tro to delete a row in a table containing list

[Satya Minnekanti]

To reproduce the defect:

1. Open any CK sample & insert a table with default values.

2. Insert a simple Numbered/Bulleted list(one list item) in one of table table cells

3. Keep cursor in a different row, open Context menu and select Row - > Delete Row.

Expected Result: Corresponding row gets deleted

Actual Result: Corresponding row is deleted but a Javascript error thrown and the error is "Unspecified error"

After that we can't get focus back in the editor. we have to close and open editor instance again

@satya with your TC I was able to reproduce the problem in IE10 and IE9.

This issue is very similar to #10308 but the former can only be reproduced in IE10 while this one in both IEs. Anyway results are the same: Unspecified error in CKE 4.x and error 800a025e in CKE 3.x.

To reproduce:

1. Insert below code into editor

   <table border="1" cellpadding="1" cellspacing="1" style="width:500px">
   	<tbody>
   		<tr>
   			<td>
   			<ul>
   				<li>test</li>
   				<li>test</li>
   			</ul>
   			</td>
   			<td>&nbsp;</td>
   		</tr>
   		<tr>
   			<td>&nbsp;</td>
   			<td>&nbsp;</td>
   		</tr>
   		<tr>
   			<td>&nbsp;</td>
   			<td>&nbsp;</td>
   		</tr>
   	</tbody>
   </table>
   <p>&nbsp;</p>
   

2. Click in cell before the list and select Rows->Delete Rows

Result: In CKEditor 4.x message that is thrown is SCRIPT16389: Unspecified Error and in CKE 3.x error 800a025e.

#8394 was marked as duplicate.

TC from that ticket:
Create a bulleted list with two items. Press enter twice to get out of the list then create a table using the default table settings. Place cursor in first cell of table, right click, delete row.

<ul>
	<li>
		Item 1</li>
	<li>
		Item 2</li>
</ul>
<table border="1" cellpadding="1" cellspacing="1" style="width: 500px;">
	<tbody>
		<tr>
			<td>
				<span></span></td>
			<td>
				&nbsp;</td>
		</tr>
		<tr>
			<td>
				&nbsp;</td>
			<td>
				&nbsp;</td>
		</tr>
	</tbody>
</table>
<p>
	&nbsp;</p>
