232924 - {inc} Offset of rel. pos. child considered for rel. pos. parent height (overflow:hidden)

Status: RESOLVED WORKSFORME

(Core :: Layout: Block and Inline, defect)

Description

[Mats Palmgren (inactive)]

A relative positioned block with overflow:hidden takes the offset of a
relative positioned child into account when computing its auto height.

STEPS TO REPRODUCE:
1. load testcase

ACTUAL RESULTS:
The overflow:hidden box seems to take the child offset into account and
is bigger than the other two.  Resizing the window fixes the problem.

EXPECTED RESULTS:
The green boxes should have the same height.

BUILDS & PLATFORMS TESTED:
Bug occurs in Mozilla nightly trunk build 2004-01-28-08 on Linux
Bug occurs in Mozilla 1.6 on Linux
Bug does NOT occur in Mozilla 1.5 on Linux

This is most likely the same problem (also fixed by resizing window).

This sounds like a block reflow issue, actually....

Did this happen with 'overflow: -moz-scrollbars-none' in 1.5?

To answer my own question, it did, so this isn't really a regression.

The bug occurs in Firefox 2004-12-05-07 on Linux,
it does not occur in Firefox 2005-09-18-06 (or later) on Linux.

The testcases are good candidates for the layout regression test suite, IMO.
