220968 - "ghost border styles appearing under a menu - regression

Status: RESOLVED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Pascal Chevrel:pascalc]

build 2003093004 WinXP

1 go to http://pascal.chevrel.free.fr/carnet/
2 look at the top link in the right menu called "Ailleurs en français"

it has a border like the borders applied to the horizontal menu, if you scroll
the page the ghost border moves up. Somehow the style applied to the horizontal
menu (a list with display:table) jumps on the other menu. This is a recent
regression, works fine with Forebird 0.6.1

This "broke" between build 2003-09-13-05 (no lines) and build 2003-09-14-05 (lines).

The most likely culprit is bug  173277.  Removing the "border-collapse:
collapse" also clears up the problem, so chances are some table code is just
painting in a totally weird spot....

I this a firebird bug, or a browser bug?
Seems to work fine with Mozilla suite:

Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.6a) Gecko/20031002 Firebird/0.7+
Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.6a) Gecko/20031002
Seen in both of them.
It is not seen if you are loading in the background, and then switch tabs.
It is seen on Shift-Reload, and vanishes on Reload, or hovering over a menu, as
done with returning from the Reload button.
Repeated Shift-Reloads are showing all sorts of different results, I´ll attach 4
small (4/16 kb) details from screenshots, as seen on Mozilla.

Mostly there is only a thin ghostline, sometimes there are multiple ghosts,
drawn fat.
