* SUMMARY The "TAKE TWO: msnbc.com" column in the right-center of the page has overlapping content in recent WebKit ToT builds. * STEPS TO REPRODUCE 1. Launch Safari/WebKit. 2. Go to URL: http://www.msnbc.msn.com/id/3032608/ 3. Look at "TAKE TWO: msnbc.com" column. * RESULTS The first item in the list overlaps the header image (see soon-to-be-attached screenshot). * REGRESSION: This is a regression from Safari 2.0.4 (419.3) with original WebKit on Mac OS X 10.4.10 (8R218). Tested with a local debug build of WebKit r27112 with Safari 3 Public Beta v. 3.0.3 (522.12.1) on Mac OS X 10.4.10 (8R218).

Works: r19672 Fails: r19697
Checking internal builds: Works: r19695 Fails: r19698
Almost certainly caused by r19696 as r19697 didn't change any table code: http://trac.webkit.org/projects/webkit/changeset/19696

TOT matches Firefox on the reduction.
(In reply to comment #6) > TOT matches Firefox on the reduction. Both Firefox 2.0.0.8 and Firefox 3.0a9pre (Oct 28, 2007) render the same was as ToT WebKit on Tiger. Opera 9.22 renders like Safari 2.0.4 (419.3) on Tiger, as does MSIE 7 on Windows XP Pro.
Created attachment 17258 [details] Reduction #1 This reduction is truer to the original page. Works in Opera 9.22 and original Safari 2.0.4, but not in Firefox 2.0.0.9 or ToT WebKit + Safari 3 Public Beta. On Tiger.
Created attachment 17259 [details] Reduction #2 This reduction does not include a table, so it is not as true to the original page. Renders as expected on Opera 9.22. Overlap occurs on Safari 2.0.4, ToT WebKit+Safari 3 Public Beta and Firefox 2.0.0.9 on Tiger.
David, Opera renders both test cases as expected due to Quirks Mode: http://www.opera.com/docs/specs/doctype/ It emulates IE bug: "Vertical overflow in block elements with a specified height In Quirks Mode, Opera will expand the block element to fit the content. In Standards Mode, Opera honours the height and applies the style overflow:visible if nothing else is specified." If you add proper DOCTYPE to your test cases Opera will start render it as Webkit, Gecko in standards mode. So we want to emulate above mentioned Opera behavior as well it should be added to Quirks Mode of Webkit. If we consider this bug in CSS standard way the bug is INVALID.
The overflow:visible issue is covered also on this page: http://www.quirksmode.org/css/quirksmode.html#t16
Thanks for the detective work, Robert!
