This test case demonstrates the incorrect behaviour in IE8 pre-RC1 where any expanded :hover (and clickable, if A element) area of an inline element is not honoured. This expanded area is due to padding value larger than 0
The expanded area of the A element is outlined using a red border; clicking anywhere inside this area should active the :hover pseudo-class state which gives this area a green background. With IE8 pre-RC1 you have to instead hover over the anchor text before the green background specified in the :hover selector is activated.
