In this test, div#parent's computed 'column-rule-color' is given by div#parent's 'currentcolor' (a reserved keyword) and not 'red'. Then div.child's 'column-rule-color' take such specified value ('currentcolor') from its parent (due to 'inherit' keyword) and not 'red'. And then, it is applied to div.child's 'column-rule-color'.
