Sort feature in association endpoint in Spring Data Rest

I have the following two resources, and their association;

@Table(name = "Item")
@Data
@Entity
public class Item {

    @ManyToOne
    @JoinColumn(name = "fk_wrapper")
    private Wrapper wrapper;

    @Id
    @GeneratedValue
    private String id;

    private Integer someValue;
}

and;

@Table(name = "Wrapper")
@Data
@Entity
public class Wrapper {

    @Id
    @GeneratedValue
    private String id;

    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "fk_wrapper")
    private List<Item> items;

    private String someField;
}

Then, first, I create a Wrapper;

POST http://localhost:8080/wrappers/
{
    "someField": "asd"
}

http://localhost:8080/wrappers/1 created, then I create two Item's, linked to this Wrapper;

POST http://localhost:8080/items/
{
    "someValue": "5",
    "wrapper": "http://localhost:8080/wrappers/1"
}

&

POST http://localhost:8080/items/
{
    "someValue": "7",
    "wrapper": "http://localhost:8080/wrappers/1"
}

After all this, when I call the endpoint http://localhost:8080/wrappers/1/items, I get the list of these two items, as expected, but what the trouble is that, I cannot seem to have a sorting feature on this endpoint. I seem to be able to sort in http://localhost:8080/items endpoint, but while fetching with association, there doesn't seem to be a sorting feature. Is this lack of sorting is intended, or am I lacking some configuration?

P.S. when I create a custom search method, for example;

@RepositoryRestResource
public interface ItemRepository extends JpaRepository<Item, String> {
    List<Item> findByWrapper_Id(@Param("id") String id, Sort sort);
}

Then I can use the sorting with http://localhost:8080/items/search/findByWrapper_Id endpoint, but too ugly imo, considering there is already an auto-generated endpoint.
