199142 - absolutely positioned content in a table cell makes table cell expand

Status: RESOLVED WORKSFORME

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021210 Debian/1.2.1-3
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20021210 Debian/1.2.1-3

Given a table cell that contains a relatively positioned div (outer) which in
turn contains an absolutely positioned div (inner), the table cell is expanded
to include the full size of the inner div. Per the standards, the inner div
should be removed from normal flow, so the table cell should be sized as if the
inner div is not present.

Reproducible: Always

Steps to Reproduce:
Visit the URL linked to this bug (http://www.sab39.org/positiontest.html

The testcase shows a 3x3 table. The middle cell of the table contains a div with
"position: relative", which in turn contains a red div with "position: absolute"
and a width and height of 100px.

Actual Results:  
Mozilla renders the table with the red div completely inside the center table
cell, expanding that cell to be large enough to fit it.

Expected Results:  
Since the inner div has position: absolute, it should be removed from normal
flow and should not affect the size of its containing table cell. Instead, the
table should be rendered as if the red div were not present, and then the red
div should be overlayed on top. Recent versions of Internet Explorer get this right.

david fixed the expansion bug a long time ago, now the abs pos div is too
small.

this is more a r&a pos bug, the table has the correct size.

URL is 404 so I recreated a testcase from the description and screenshots.

Well, the problem seems to be solved.
I still see the wrong rendering in:
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/2003-12-16
Firebird/0.7+

But when using Mozilla1.7RC2, I see the correct rendering.
