In the test case the style property 'position' is changed from 'static' to 'relative'. This change makes Safari (and Firefox and Chrome) return different offsetLeft and offsetTop values. If you add the border width of 15px to those values you get the correct results again. If you open the test case in Internet Explorer and Opera you'll see that they return the same values no matter what 'position' is set to. 111926 1 28202 boris 2009-03-02 16:07:59 -0800 Created attachment 28202 Test case to reproduce the bug 321933 2 76530 playmobil 2010-12-14 06:19:28 -0800 Created attachment 76530 Another testcase 321935 3 playmobil 2010-12-14 06:25:21 -0800 Chromium bug: http://crbug.com/15535 Bug 26020 may also be related to this issue.
