Completion of nested property of generic source property

Example Source class (Lombok used for brevity):

import org.geolatte.geom.G2D;
import org.geolatte.geom.Point;

@Getter
@Setter
public class Location {
    private Point<G2D> coordinates;

    // ...
}

eg. when attempting to map the latitude of coordinates:

@Mapping(source = "coordinates.position.lat", target = "latitude")

Point#getPosition() returns the type argument, in this case G2D, but the plugin infers it as P (the type parameter), and hence fails to autocomplete the G2D#getLat() property.

Reproduce the nested mapping example with Location, Point, and coordinates.position.lat in IntelliJ IDEA. Start by tracing how the plugin resolves Point#getPosition() and its generic type argument, then verify autocomplete reaches G2D#getLat(). Done means the property is suggested as G2D rather than the unresolved type parameter P.
