INSERTIONS are lost, no ERROR reported for out-of-range values in STRICT mode

insertion of -128 works for MyISAM

mysql> create table t2(c1 tinyint) ENGINE=MYISAM;
Query OK, 0 rows affected (0.01 sec)

mysql> insert into t2 values(-128);
Query OK, 1 row affected (0.01 sec)

mysql> select * from t2;
------

------

------
1 row in set (0.00 sec)

mysql> drop table t2;
Query OK, 0 rows affected (0.00 sec)

value is "conformed" to smallest possible value on ColumnStore:

mysql> create table t2(c1 tinyint) engine=columnstore;
Query OK, 0 rows affected (0.39 sec)

mysql> insert into t2 values(-128);
Query OK, 1 row affected, 1 warning (0.17 sec)

mysql> show warnings;
-----------------------------------------------------------------

-----------------------------------------------------------------

-----------------------------------------------------------------
1 row in set (0.00 sec)

Note above error does not have properly error code or error message, it should be

error=1264, error message=Out of range value for column 'c1' at row 1

mysql> select * from t2;
------

------

------
1 row in set (0.06 sec)

STRICT_MODE should result in ERROR and no row insertion

mysql> set sql_mode=STRICT_ALL_TABLES;
Query OK, 0 rows affected (0.00 sec)

Columnstore says one row was inserted, but raises warning:

mysql> insert into t2 values(-128);
Query OK, 1 row affected, 1 warning (0.06 sec)
mysql> show warnings;
---------------------------------------------------------------

---------------------------------------------------------------

---------------------------------------------------------------
1 row in set (0.00 sec)

Again, note above error does not have properly error code or error message, it should be

error=1264, error message=Out of range value for column 'c1' at row 1

INSERTION FAILED BUT QUERY RETURNED 1 ROW INSERTED!
mysql> select * from t2;
------

------

------
1 row in set (0.01 sec)
