The URL takes you to a reduction that demonstrates the issue. This is complex because FF3 and IE7 don't agree 100%. FF3 and IE7 agree on the table, but disagree on the DIV. WebKit and Chromium 0.3.155.0 agree with FF3 on the DIV and disagee with both IE7 and FF3 on the table. This is being tracked in Chromium as http://code.google.com/p/chromium/issues/detail?id=1144

I took the test from Chrome bug: JSFiddle - https://jsfiddle.net/t8sh7yrL/show It is still broken in STP158, which has negative margin fix but it is less broken than Safari 16.1, so at least it is a win.

WebKit ToT (261814@main) is now matching all other browsers. Marking this as “RESOLVED CONFIGURATION CHANGED”. Must be IFC progression. Thanks!

While I am more than happy to take credit for this, I think this is some "random" block layout progression (and not IFC).
