[Webkit] "Delete Columns" sometimes removes two columns instead of one

[Karen Ananiev]

• Create 3x3 table and type any char in the first cell
  
• Double click to the right of the char (the char should not be selected, but cell will. See video: ​http://www.screencast.com/t/XIGCstjiDti ). Or you can use Shift+Right arrow key.
  
• Right click -> Column -> Delete Columns

Outcome: the first and the second columns will be deleted
Expected: only the first column deleted

1. Insert below code into editor and switch to WYSIWYG:

   <table border="1" cellpadding="1" cellspacing="1" style="width: 500px;">
   	<tbody>
   		<tr>
   			<td>
   				1</td>
   			<td>
   				2</td>
   			<td>
   				3</td>
   		</tr>
   		<tr>
   			<td>
   				&nbsp;</td>
   			<td>
   				&nbsp;</td>
   			<td>
   				&nbsp;</td>
   		</tr>
   		<tr>
   			<td>
   				&nbsp;</td>
   			<td>
   				&nbsp;</td>
   			<td>
   				&nbsp;</td>
   		</tr>
   	</tbody>
   </table>
   

2. Click behind 1. and press Shift+Right arrow
3. Select delete columns from right-click menu

Problem can be reproduced in Blink and Webkit from CKEditor 4.0.1
