Open fast/box-sizing/box-sizing.html in Safari and then look at the pixel dump that's checked in. They don't look the same.
New results for this test were checked in by Justin on 2006-02-16 (both old and new passed the test criteria): http://trac.webkit.org/projects/webkit/browser/trunk/LayoutTests/fast/box-sizing/box-sizing-expected.png?rev=12842 http://trac.webkit.org/projects/webkit/browser/trunk/LayoutTests/fast/box-sizing/box-sizing-expected.png?rev=11946 Does this issue need further investigation?
No answer in two years, closing now. The test is not very clear on its expectations ("All of the boxes below should be 20x20 and look identical."). The boxes certainly do look the same, but there are images inside them that don't. My understanding is that the test passes anyway.
