Steps to reproduce:
1. Open http://demos.telerik.com/aspnet-ajax/editor/examples/builtincontentfilters/defaultcs.aspx

2. Clear the content of the Editor, swith to html mode and paste the following content:
test
<a href="http://demos.telerik.com/aspnet-ajax/editor/examples/builtincontentfilters/defaultcs.aspx" target="_self">2.2.2</a>
<br>
<table bordercolor="#000000" border="1" cellspacing="0" cellpadding="2">
    <tbody>
        <tr>
            <td style="text-align: center; vertical-align: middle;" rowspan="2"><strong>Text</strong></td>
        </tr>
    </tbody>
</table>


3. Switch to Design mode and back to html mode.

test
<a href="#000000" border="1" cellspacing="0" cellpadding="2">
     
         
            <strong>Text</strong>
