In the page at http://chrys.myphotos.cc/bug.html, each time you put the mouse
over the "Voir les commentaires" link, the :hover comportment is ok
(border-bottom), but the li block width's decrease, whereas it shouldn't.
If I replace border-bottom with text-decoration for example, everything is fine
(but i can't change the color of the underline).

This bug is also available on Mozilla 1.7 and Firefox for Windows.
Konqueror isn't affected, nor IE.

Reproducible: Didn't try
Steps to Reproduce:
I haven't tried to reproduce the bug, but here is some tips :

1. The li block has a non fixed width (it's 70%). When i change to something
fixed (like 500px), the bug doesn't appear


Expected Results:  
The link should have got a black border at bottom, and the li block should keep
it's actuel size

I can also see the bug with:

Firefox/0.9.1+

The first testcase depends on -moz-outline causing a reflow which it did not
do until recently.  This testcase is closer to the original.

The bug does NOT occur in Mozilla 1.1 on Linux.
The bug occurs in Mozilla 1.2 and later on Linux.

I dont know if it can help, but the first testcase work as expected here (i
mean, there is no bug) ...
Tested on Mozilla/5.0 (X11; U; Linux i686; rv:1.7.3) Gecko/20041002
Firefox/0.10.1 and Mozilla 1.7.3

This is not limited to abs. positioning, in both testcases you could replace 
position:absolute with float:left and get the same bug.

The abs.pos. case appears to have been somewhat fixed by bug 201897... but it's
still not correct.

Fixed on trunk by reflow branch landing.
