Widget Interface: Conflicts when using Clear() and SetItem()

When running the W3C Test Case "au", Wookie fails to correctly set a value after calling clear() first and then reloading the page.

This is likely caused by the clear() process executing and overriding the subsequent (in script order terms) setItem() call, either on the client side or server side.

To replicate, use this widget:
