That still makes sense to me, because the group is placed on this card and the button belongs to the group, so I would expect the message path to take the normal route, i.e. Button, Group, Card, Stack, why would it not?
But when clicking on the card, the background is picking up the stray mouseUp message passed on from the card before it reaches the stack.
