Inconsistent Comparison Results for DATETIME and String Values Between MySQL 5.7 and MariaDB

There is a discrepancy between MySQL 5.7 and MariaDB when performing a SELECT query involving a comparison between a DATETIME column and a non-date string.

Create the table and insert the values:

CREATE TABLE t0 (c DATETIME);

INSERT INTO t0 VALUES ('2021-09-10 06:35:35.000000');

Execute the following query:

SELECT t0.c FROM t0 WHERE t0.c > 'k3dHE';

MariaDB Results:
2021-09-10 06:35:35

MySQL 5.7 Results:
