Split non-header cell in table with <thead> throws JavaScript error

[shri]

Tested below steps on trunk samples default page in FF and IE

1. Create a 3x2 table with first row header.
2. Split non-header cell horizontally and JS error is thrown.
3. Also splitting non-header cell vertically breaks the table layout.

1. Insert source:

   <table cellspacing="1" cellpadding="1" border="1" width="200">
       <thead>
           <tr>
               <td>11</td>
               <td>22</td>
           </tr>
       </thead>
       <tbody>
           <tr>
               <td>33&nbsp;</td>
               <td>44&nbsp;</td>
           </tr>
           <tr>
               <td>55&nbsp;</td>
               <td>66&nbsp;</td>
           </tr>
       </tbody>
   </table>
   <p>&nbsp;</p>
   

2. In WYSIWYG. right-click 33 > Cell > Split cell horizontally

You've got an error:

Does not occur in CKEditor.

Since FCKeditor is no longer supported and recommend upgrading to CKEditor I'm closing this ticket as it is no longer valid.
