[IE] Unable to move cursor between hr and table

[Garry Yao]

1. Load an editor with the following content and selection:

   <table border="1" cellpadding="1" cellspacing="1" style="width: 200px;">
   	<tbody>
   		<tr>
   			<td>
   				text^</td>
   		</tr>
   	</tbody>
   </table>
   <hr />
   

2. Try to move cursor after table by press 'Right Arrow' key;

• Actual Result: It's impossible to move cursor exactly after the table and before the HR, and lots of dummp paragraph generated at the end of this document.
