list-style-image value not being reset by subsequent list-style shorthand property

This test case demonstrates the incorrect behaviour of IE8 RTW where a list-style-image value is not being reset by a subsequent list-style shorthand property

Live Example

Since the list-style property appears after the list-style-image property in the declaration block, the comparative value in the list-style overrides the list-style-image value. In the case where there is no comparative list-style value, then the list-style-image value within this shorthand notation is reset to 'none' (its initial value), as per 1.4.3

In the example below, you should see no image and instead see the 'number 1' followed by a decimal, outside of the principal block box of the list-item.
