What's Wrong?

when we use fold constant in fe, it shows different result with be execute directly
mysql [(none)]>select str_to_date('2024-09-06 15:41:08', '%Y-%m-%d %T');
+---------------------------------------------------+
| str_to_date('2024-09-06 15:41:08', '%Y-%m-%d %T') |
+---------------------------------------------------+
| 2024-09-06 15:41:08 |
+---------------------------------------------------+
1 row in set (0.00 sec)
mysql [(none)]>set DEBUG_SKIP_FOLD_CONSTANT = true;
Query OK, 0 rows affected (0.00 sec)
mysql [(none)]>select str_to_date('2024-09-06 15:41:08', '%Y-%m-%d %T');
