When a style has been defined for the anchor element (i.e.
  a:hover { background: yellow; }
an empty named anchor within a table cell causes that defined anchor style to be
applied from the anchor on to the end of the cell.

Reproducible: Always
Steps to Reproduce:
1. Load the attached sample document with the Mozilla browser
2. Hover with the mouse over each cell.


Actual Results:  
Table cell one does not contain a named anchor.  Hovering over it does not have
any effect.
Table cell two contains a named anchor between the first and second line.
Howering over the second line displayes the background as yellow.
Table cell three contains a named anchor at the beginning of the cell.  Hovering
over the cell displayes the background of the cell as yellow.

Expected Results:  
The background color should not change for table cell two or three.

     A drug that is used in the treatment of acne and psoriasis and is being 
     studied in cancer prevention. It belongs to the family of drugs called 
     retinoids. Also called isotretinoin.<a name='foo'/></span>
    </td>
   </tr>
  </table>
 </body>
</HTML>
a:hover applies to anchors as well as links.  So since you haven't closed the
anchors (you can't use <a /> in an HTML document, the anchor is open in the
table cell and :hover affects the color appropriately.

This is what should happen given your code.  Invalid.
