Can we update a RelationshipEntity to point to a different NodeEntity?

Using Neo4j-OGM I'm trying to update a @RelationshipEntity to point to a different node object. But when I try to persist the change, it doesn't get saved, it just reverts back to the original entity.

For example, this is what I want to achieve:

from:    (X)--[R]->(M)    (Y)

  to:    (Y)--[R]->(M)    (X)

I've made an example in the CineastsRelationshipEntityTest integration test:

@Test
public void canUpdateRelationshipEntity() {
    Movie movie = new Movie("M", 2020);

    Actor actor = new Actor("X");
    Role relationship = actor.playedIn(movie, "R");

    Actor actor2 = new Actor("Y");
    actor2.setRoles(new HashSet<>());

    assertThat(actor.getRoles()).hasSize(1);
    assertThat(actor2.getRoles()).hasSize(0);

    session.save(actor);
    session.save(actor2);

    session.clear();


    // try to update the relationship:
    relationship.setActor(actor2);
    actor.getRoles().remove(relationship);
    actor2.getRoles().add(relationship);

    assertThat(actor.getRoles()).hasSize(0);
    assertThat(actor2.getRoles()).hasSize(1);

    session.save(actor);
    session.save(actor2);

    session.clear();



    Actor loadedActor = session.load(Actor.class, actor.getUuid());
    Actor loadedActor2 = session.load(Actor.class, actor2.getUuid());

    assertThat(loadedActor.getRoles()).hasSize(0);
    assertThat(loadedActor2.getRoles()).hasSize(1);
}

At the end, loadedActor and loadedActor2 do not reflect the updated relationship.
