Major 3.9 update errors, code disappears

Some of my code disappears after editing on a page.
I have this code in a page:

<table style="height: 25px; background-color: #fd9500; ; width: 150px;" border="0">
<tbody>
<tr>
<td style="width: 150px; height: 25px;" align="center" valign="middle"><span style="color: #000080;"><a href="#"><span style="color: #000080;">Pris</span></a></span></td>
</tr>
</tbody>
</table>

After update if I want to edit a page and then save the code changes to this:

<table style="height: 25px; background-color: #fd9500; ; width: 150px;" border="0">
<tbody>
<tr>
<td style="width: 150px; height: 25px;" align="center" valign="middle"><span style="color: #000080;"><a href="#"><span style="color: #000080;">Pris</span></a></span></td>
</tr>
</tbody>
</table>
