Partition PAGE_COMPRESSED accepts an invalid boolean that table-level validation rejects

MariaDB accepts and persists PAGE_COMPRESSED='not_a_boolean' when the option is placed on a partition, although the same value at table scope is rejected with ERROR 1912. No IGNORE_BAD_TABLE_OPTIONS mode is enabled.

Steps to reproduce

1. Save the database setup as setup.sql:

CREATE DATABASE validation;

2. Save the table-level control as control.sql:

USE validation;

SET SESSION sql_mode='STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION';

CREATE TABLE control (id INT) ENGINE=InnoDB PAGE_COMPRESSED='not_a_boolean';

3. Save the partition-level case as case.sql:

USE validation;

SET SESSION sql_mode='STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION';

CREATE TABLE partitioned (id INT) ENGINE=InnoDB

PARTITION BY HASH(id)

(PARTITION p PAGE_COMPRESSED='not_a_boolean');

SHOW WARNINGS;

SELECT 'ACCEPTED_INVALID_OPTION', COUNT(*) FROM information_schema.TABLES

WHERE TABLE_SCHEMA='validation' AND TABLE_NAME='partitioned';

SHOW CREATE TABLE partitioned;

4. Execute the files in order with separate MariaDB client invocations:

mariadb --batch --raw < setup.sql

mariadb --batch --raw < control.sql

mariadb --batch --raw < case.sql

The control invocation is expected to report an error; continue with case.sql afterward.

Actual result

The table-level control rejects the value:

ERROR 1912 (HY000): Incorrect value 'not_a_boolean' for option 'PAGE_COMPRESSED'

The partition-level statement succeeds without a warning. The table exists, and SHOW CREATE TABLE retains the invalid value:

ACCEPTED_INVALID_OPTION  COUNT(*)

ACCEPTED_INVALID_OPTION  1

Table        Create Table

partitioned  CREATE TABLE `partitioned` (

  `id` int(11) DEFAULT NULL

) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_uca1400_ai_ci

 PARTITION BY HASH (`id`)

(PARTITION `p` ENGINE = InnoDB `PAGE_COMPRESSED`='not_a_boolean')

Expected result

PAGE_COMPRESSED is a boolean option, so 'not_a_boolean' should be rejected at partition scope with the same bad-option diagnostic produced at table scope. The partition definition should not be created or persisted with that value.

This occurs when a boolean engine option is supplied on a partition definition rather than at table scope.
