Highlighting is incorrect on tables.

[japo32]

It seems like it has trouble highlighting changes on tables when then contents of the cells are similar.

originalHTML = 
<table>
<tbody>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
</tbody>
</table>;

 newHTML = 
<table>
<tbody>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
</tbody>
</table>

 originalHTML2 =
<table>
<tbody>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
</tbody>
</table>;

 newHTML2 =
<table>
<tbody>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
</tbody>
</table>;

originalHTML3 = 
<table>
<tbody>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
</tr>
</tbody>
</table>;

 newHTML3 = 
<table>
<tbody>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>kkk</td>
</tr>
<tr>
<td>kkk</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
<tr>
<td>asd</td>
<td>asd</td>
<td>asd</td>
<td>sd</td>
</tr>
</tbody>
</table>;
