I always considered groups as being a single object.  It sounds a bit
weird for another object to be `in between' a group.  Maybe creating a
group shouldn't cause the objects to raise to the top of the stack, but
grouped objects have always acted as one position in the depth stack in
all the drawing software I have used.
