[CLOSED-101] Top and Bottom dock failing
I've got a List with both top and bottom docked items. The top item is a datapanel, the bottom some buttons. The top datapanel is not layed out properly. You can see it by going here:
Click on "Place an Order", "Drinks", "Coffee"
This code also shows another bug (that it works around) which is that in a card layout in a panel where more than one panel has bottom-docked buttons, inactive panel button handlers get fired. You can see this in doOptionAdd and addCart.
