Steps to reproduce or a small repository showing the problem:

        const example = await Example.findOne(
          {  id  },
          { relations: ["parent", "parent.childOne", "parent.childTwo", "other"] }
        );

In this example, if Example entity's parent relation is eager: true, then childOne and childTwo will not be loaded as requested.

  @ManyToOne(
    () => Parent,
    (parent: Parent) => parent.example,
    {
      eager: true // disabling this and the above code will load nested relations
    }
  )
  @JoinColumn()
  parent: Parent | null;
