I gather from this article that its orbital radius varies between 65 AU and 2300 AU, which is an extremely eccentric ellipse. I wonder if that high eccentricity would disqualify it from "planet" status. Most other bodies considered "planets" are far closer to circular.
It's also unclear to me if the Goblin orbits in the usual planetary plane.
