As pictured in the following screenshot sometime the table is stretched
out. It happens 90% of the time on any given page (except splash page) at
http://www.clsclacsaintlouis.qc.ca/. This behaviour wasn't in 1.5 RC-1 or any
previous Mozilla versions so it has been induced between 1.5 RC-1 and 1.5 RC-2.
I can reproduce under MacOS X on multiple computers (test on 3 computers) but
can't reproduce under Windows 98 with the same version 1.5 RC-2. Pages are PHP
generated (I've tested on two different servers and got the same result), so I
guess that Moz doesn't reflow table after the page download is completed.
Reloading the page doesn't fix the problem but a force reload (shift+refload)
does. Finally a local copie of the page always loads flawless...  or a static
one... http://www.clsclacsaintlouis.qc.ca/test.html  

Reproducible: Always

Steps to Reproduce:
1. Browse http://www.clsclacsaintlouis.qc.ca/ under MacOS X with 1.5 RC-2
2. Browse, browse and see
3.

Actual Results:  
Table stretched

Expected Results:  
No stretch

I see this on winxp 2004092206 too we would need a reduced testcase here

Attachment: Testcase for bug 220982

I could not get this testcase any smaller, it seems to depend on a few
different things:

- the nested table,
- floats with left or right padding or margin in another container in a table
cell,
- the width of the last column being defined in the last row.

Weirdness observed with:
-  Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/2006120606 Minefield/3.0a (pre-reflow branch)
(Loading 'Testcase for bug 220982' and then repeatedly making font bigger and smaller with CTRL++ and CTRL+- has strange effects.)

No weirdness observed with:
- Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.9a1) Gecko/2006120804 Minefield/3.0a1 (post-reflow branch)
(Loading 'Testcase for bug 220982' and then repeatedly making font bigger and smaller with CTRL++ and CTRL+- doesn't incrementally widen the cell width. Or something.)

-->RESOLVED FIXED ?

Bug occurs in SeaMonkey 2006120701 (pre reflow branch) on Linux.
Bug does not occur in SeaMonkey 2006120801 (post reflow branch) on Linux.

-> FIXED (by the reflow branch landing)
