That guess is almost right - with invalid input like this, the HTML5 
parser moves the <span> to just before the <table>, so it's equivalent to:

   <span about="#2105555" typeof="foaf:Person"></span>
   <table>
     <tr>
       <td>1</td>
       ...
     </tr>
   </table>

(You can test how html5lib parses HTML into a DOM tree using
