Problem with width and height of a table

Hi,

if you paste this code in ckeditor :

<table width="300" height="200">
   <tbody>
      <tr>
         <td>
            foo
         </td>
      </tr>
   </tbody>
</table>

While accessing to the properties of the table, the width and height appears and disappears very quickly. And if you enter values and validate. Go into the source, and you'll see a style attribute is added while width and height attributes are still present. (tried with the last revision 6115)

Hope it can be solved !
Thanks in advance.
