This can be reproduced in your online demo. Copy this code into your XHTML demo online in HTML view:
<table style="margin-left: auto; margin-right: auto" cellpadding="5">
<tbody>
<tr>
<td style="width: 100%; text-align: center" valign="top"><a href="http://www.google.com/" target="blank"><img style="border-right: medium none; border-top: medium none; border-left: medium none; width: 72px; border-bottom: medium none; height: 47px" alt="" src=
http://www.google.com/logo.gif /></a> <br />
<strong><span><a href="http://www.google.com/" target="_blank">Google</a></span></strong></td>
</tr>
</tbody>
</table>
Switch to Normal view, then back to HTML view. All of the style attributes have doubled, like this:
<table style="margin-left: auto; margin-right: auto" cellpadding="5" style="margin-left: auto; margin-right: auto">
<tbody>
<tr>
<td style="width: 100%; text-align: center" valign="top" style="width: 100%; text-align: center"><a href="http://www.google.com/" target="blank"><img style="border-right: medium none; border-top: medium none; border-left: medium none; width: 72px; border-bottom: medium none; height: 47px" alt="" src="http://www.google.com/logo.gif" style="border-right: medium none; border-top: medium none; border-left: medium none; width: 72px; border-bottom: medium none; height: 47px" /></a>
<br />
<strong><span><a href="http://www.google.com/" target="_blank">Google</a></span></strong></td>
</tr>
</tbody>
</table>
