NodeModel.positionChanged recognizes state updates as a position update

[amonrperes]

Our company uses react-diagrams as a major feature of our system. Recently we noticed that when one of our nodes updates it's state without being moved from it's current position, the 'positionChanged' method is triggered. We had to create an algorithm to detect whether the node changed it's position using the NodeModel.getPosition.

Is this behaviour correct?
