The attached test case does not render properly. To see the bug, counters need to be implemented (http://bugzilla.opendarwin.org/show_bug.cgi?id=4980), but I have not yet committed that patch, so this bug is not yet present in the nightlies. I am filing it anyway in anticipation.

For completeness, the tests attachment #288029 [details] and http://dbaron.org/css2.1/tests/imported-20050702/t1204-reset-0{1, 2}-c-o.xht are analogous to LayoutTests/fast/css/counters/counter-reset-00{0, 1, 2}.html.
