## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)

```sql
DROP TABLE IF EXISTS t0;
DROP TABLE IF EXISTS t1;
CREATE TABLE t0(c0 INT UNSIGNED , PRIMARY KEY(c0));
CREATE TABLE t1 LIKE t0;
INSERT INTO t0(c0) VALUES (0), (2089861764);
INSERT INTO t1(c0) VALUES (209221961), (0), (1423501587);

SELECT true
FROM t0
RIGHT JOIN t1 ON t0.c0 = t1.c0
WHERE (NOT (t1.c0 OR t0.c0) IS FALSE);
```

### 2. What did you expect to see? (Required)
mysql execute result
```shell
mysql> SELECT true
-> FROM t0
-> RIGHT JOIN t1 ON t0.c0 = t1.c0
-> WHERE (NOT (t1.c0 OR t0.c0) IS FALSE);
+------+
| true |
+------+
| 1 |
| 1 |
+------+
2 rows in set (0.00 sec)

mysql> select version();
+-----------+
| version() |
+-----------+
| 8.4.1 |
+-----------+
1 row in set (0.00 sec)
```
### 3. What did you see instead (Required)
```shell
mysql> SELECT true
-> FROM t0
-> RIGHT JOIN t1 ON t0.c0 = t1.c0
-> WHERE (NOT (t1.c0 OR t0.c0) IS FALSE);
