SELECT DISTINCT...ORDER BY for partitioned tables is not working properly

When doing SELECT DISTINCT ... ORDER BY on a partitioned table, the ordering is wrong:

MariaDB [master_biz]> create table bugtest (id int not null, status int not null, descr varchar(255), primary key (id, status)) engine=innodb partition by list(status) (partition s1 values in (0,1,2), partition s2 values in (3));

MariaDB [master_biz]> insert into bugtest values (1,0,'1/0'), (3,0,'3/0'), (5,0,'5/0'), (2,3,'2/3'), (4,3,'4/3'), (6,3,'6/3');

Without DISTINCT:
MariaDB [master_biz]> select id, descr from bugtest order by id limit 0,4;

With DISTINCT:
MariaDB [master_biz]> select distinct id, descr from bugtest order by id limit 0,4;

The order of id's works only within a partition; When we do DESC sorting then things appear to be fine:

mysql [localhost]

(test) > select distinct id, descr from bugtest order by id desc limit 0,6;
