Safari: up/down arrow keys issue when working with cells

[Wiktor Walc]

When using Safari 5.0.2 @ Mac, pressing the down arrow results in moving to the next cell on the right side instead of to the cell at the bottom.

Steps to reproduce

• Using the following table:

  <table border="1" cellpadding="1" cellspacing="1" style="width: 500px; ">
  	<tbody>
  		<tr>
  			<td>
  				1</td>
  			<td>
  				2</td>
  		</tr>
  		<tr>
  			<td>
  				3</td>
  			<td>
  				4</td>
  		</tr>
  		<tr>
  			<td>
  				5</td>
  			<td>
  				6</td>
  		</tr>
  	</tbody>
  </table>
  

• go to the first cell, press "down" arrow key
• result: cursor is now in cell "2" instead of in cell "3"
