## Bug Report

### 1. Minimal reproduce step (Required)
```sql
CREATE TABLE `json_t` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`json_c` json DEFAULT NULL,
PRIMARY KEY (`id`)
);

INSERT INTO `json_t`(`json_c`)
VALUES
('{"name": "tanaka", "gender": 1, "options": {"x": 100, "y": 200}}'),
('{"name": "yamada", "gender": 2, "options": {"x": 300}}'),
('{"name": "suzuki", "gender": 1, "options": {"x": 100, "y": 200, "z": [1, 3, 4]}}');

set session tidb_opt_projection_push_down='ON';
explain analyze SELECT `json_c`->"$.name" FROM `json_t`;
explain analyze SELECT `json_c`->"$.name" FROM `json_t` limit 3;

alter table json_t set tiflash replica 1;

explain analyze SELECT `json_c`->"$.name" FROM `json_t`;
explain analyze SELECT `json_c`->"$.name" FROM `json_t` limit 3;
```
