table column width incorrectly accounts for non-flowed content width

What steps will reproduce the problem?
Create a table with two cells where one cell contains only an absolutely 
positioned element.

What is the expected output? What do you see instead?
When rendered the column with the positioned element should render with a width 
similar that that of an empty cell. Instead it is rendered to the width of the 
positioned element.

Confirmed in trunk r493.

Simple test case:
<table border="1"><tr>
<td><div style="position: absolute;">positioned div with some text</div></td>
<td></td>
<td>A normal table cell with a little bit of text</td>
</tr></table>
