Well, what do you expect when you add an inner way (the building) to an 
area object (the administrative region)? Never mind any additional tags. 
It will be interpreted as such: a gap in the area. An enclave, in this 
particular case, with an appropriate line drawn around the building.

So there you have it: don't add stuff to area datatypes that doesn't 
belong in them.
