Table CHECK constraint pretends to work but breaks transactional properties

drop table if exists t1;

create table t1 (a int, b int, check(a>b)) engine=Columnstore;

insert into t1 values (1,0),(2,2);

select * from t1;

insert into t1 values (3,0);

select * from t1;

MariaDB [db]> insert into t1 values (1,0),(2,2);

ERROR 4025 (23000): CONSTRAINT `CONSTRAINT_1` failed for `db`.`t1`

MariaDB [db]> select * from t1;

Empty set (0.055 sec)

MariaDB [db]> insert into t1 values (3,0);
