User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7) Gecko/20040614 Firefox/0.9

Coding a simple site I ran by this problem.
There is a menu, with some 6 elements like this:

<a href="#"
onmouseover="javascript:document.getElementById('hint1').style.visibility='visible'"
onmouseout="javascript:document.getElementById('hint1').style.visibility='hidden'">Menu
1</a>

in a table.
Right after the table there are 6 corresponding divs with descriptions, like this: 

<div id="hint1" style="visibility:hidden; position:absolute">
   <table width="100%" border="0" cellpadding="0" cellspacing="0">
   <tr height="20">
    <td background="images/gr2.gif" align="center">Description 1</td>
   </tr>
  </table>
 </div>

The problem is when I run Firefox and open the page, it leaves small piece of
horizontal blank space between the table with menu and the div; when I hit
refresh or reopen the page, the space disappears.

The zip with the whole page is attached.

Reproducible: Always
Steps to Reproduce:
1. Run Firefox, make and open the page with above code, see the problem
2. Hit refresh
3. See the problem disappear

Actual Results:  
Upon the first run Firefox displayed the page incorrectly, adding some blank
space, which got fixed by refreshing or reopening the page.

Expected Results:  
It should have shown the page without blank space right upon opening, not having
to hit the refresh button.

This bug is old and many changes have been made to the rendering engine since it
was filed. Please reopen the bug if you can still reproduce with a recent nightly.
