Bogus br when Insert table cell

[Garry Yao]

Table cell insertion logic should be optimized to be filled with bogus BR instead of hard BR.

Reproducing Procedures

1. Open the replace by class example page;
2. Clear all document content, and open 'Table' dialog to Insert a 1x1 table;
3. Switch to 'Source' mode.
   • Actual Result: Extra BRs displayed in source code.

     <table border="1" cellpadding="1" cellspacing="1" style="width: 200px;">
     	<tbody>
     		<tr>
     			<td>
     				<br />
     			</td>
     		</tr>
     	</tbody>
     </table>
     <p>
     	<br />
     </p>
     

   • Expected Result:

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