Status: RESOLVED DUPLICATE of bug 308521

I'll attach the testcase.
This worked in 2005-08-22 trunk build, but fails in 2005-08-23 trunk build, so
I'm guessing a regression from bug 296036.

This seems to also effect links when they or an ancestor has a negative left
margin inside of a fixed element, as on http://www.w3.org/Style/ . I can click
on the navigation links, but not exactly where I should be able to (the right
side of the links isn't clickable/hoverable when it should be, and the area to
the left of the links is clickable/hoverable when it shouldn't be).

The fix for clipping in bug 305944 doesn't fix this regression bug. Tested with:

SeaMonkey: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1)
Gecko/20050901 SeaMonkey/1.1a
Firefox: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1)

... and the post before it.

I suspect it is the same issue, so that's why I'm posting this second testcase
here.

Summary of: http://forums.mozillazine.org/viewtopic.php?p=1740878#1740878

Fixed menu at http://www.w3.org/Style/CSS/ seems to have clickable area offset
in current builds. Using EditCSS to change the rule:

body>div#Menu, body>div.map { position: fixed }

to:

body>div#Menu, body>div.map { position: absolute }

... resolved the clickable area issue. Curiously, the links only have
text-indent set to "0", so the offset seems to be dependant on margin/padding too...

Fix as suggested in bug 308521 works as expected with sites reported in bug
308521 and bug 306179 and all test-cases in said bugs.

Texted with build:

Yes, this is already fixed. Like Jonathan said, very likely fixed by bug 308521.
