User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a4) Gecko/20040927
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a4) Gecko/20040927

Three column CSS page with left and right columns floated inside margins of main
column.

Hovering mouse over any link in main center column causes content of main column
to be repositioned below bottom edges of left and right columns (usually off
bottom of visible screen). Resizing screen restores content to correct location.

Behaviour is not present in release 1.7.3 or in Firefox 1.0PR

Reproducible: Always
Steps to Reproduce:
1. Go to page http://www.scotland.gov.uk/Home
2. When page is fully loaded center column will shift to below sidebars
3. Resize page and center content reappears in normal location
4. Hover over any link in center column and content moves to bottom again




Also occurs on all other top level two and three column pages in the Topics,
About, News and Help sections of the website (e.g.
http://www.scotland.gov.uk/Topics)

The testcase was fine, but I removed the following css rule:
a:hover {	border-bottom:1px solid #f00; }
This could potentially cause margin-decollapsing of two adjacent blocks.
This is not happening here, but better have no doubt about that.

I've tried the "diff -w" patch from bug 209694 in my debug build and it seems to
fix this bug.
