Maybe not a bug per se, since the Power Net Portal works, but the implementation is definitely confusing to me. When I change the Power Net Portal designator name, I expect the net designator name attached to the Power Net Portal to change with it. Ie, if I make the Power Net Portal design "VBUS", I expect the Net designator to also be "VBUS". Right now the Net designator matches what appears to be the first connection made to the Power Net Portal.
