278720 - Wrong table width on the first page load right after loading Mozilla or Firefox

Status: RESOLVED WORKSFORME

(Core :: Layout, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041217
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041217

Right after the Mozilla or Firefox startup, the first time (and only the first)
I load the page I often find the width of the nested table (see the example)
wrong (it's a 30% width but is displayed as 100%). After some test the problem
seems to be affected by the network speed (higher speed, easier to see the problem).

Reproducible: Sometimes

Steps to Reproduce:
1. Start Mozilla or Firefox (close and start again the browser if just opened)
2. Load the page http://neurotix.com/bugzilla/page.htm (or save it to disk and
open it from the local drive)
Actual Results:  
The centered nested table is often displayed with 100% width instead of 30%.

Expected Results:  
The centered nested table should be displayed with a 30% width.

The problem occours only if the page is loaded after the browser startup and
only if the nested table width (see test case) is relative (percentage - if you
set the size in pixels there's no problem). I experience this problem about the
90% of the times I load that page for first after loading the browser (I found
the same problem in Firefox 1.0).
Also the network speed seems to affect the frequency the problem appears: with a
fast network connection (LAN, local drive, T1, etc.) the problem occours quite
everytime you load the page.
I have noticed that removing the images (blanked for privacy issues) on the top
of the page seems to prevent the problem to happen.

I can't see the bug, using Mozilla1.7 or the latest trunk build.
Reporter, can you still see the bug, using the latest nightly trunk build?

The problem seems resolved with the latest nightly build (tested right now with:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050117).
Using the latest nightly built of the 1.7 trunk the problem is still unresolved
(tested with: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6)
Gecko/20050112).
With the 1.7 version I easily experience the problem.

Worksforme, per comment 2... Please reopen if this is reproducible in a trunk
build (and note that 1.7 is a branch, not the trunk).
