macvtap with disconnected physical interface

Dear list, I just discovered the hard way that if the lower lever physical interface of a macvlan bridge is disconnected (ie: by unplugging the eth cable, resulting in no carrier), inter-guest network traffic from all virtual machines bound to the disconnected interface is dropped. This behavior surprises me, as with the classic bridges I can disconnect the underlying physical interface without causing any harm to inter-guest traffic. Am I doing something wrong, or this really is the expected behavior? If so, can I force the macvtap interfaces to bridge traffic even when the underlying physical interface is disconnected?
