## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)
run SQL
```sql
SET @@global.MAX_EXECUTION_TIME = 30000;
CREATE DATABASE region_merge;
CREATE TABLE region_merge.t1 (id bigint primary key);
SPLIT TABLE region_merge.t1 BETWEEN (-9223372036854775808) AND (9223372036854775807) REGIONS 40;
SELECT count(distinct region_id) from information_schema.tikv_region_status where db_name = 'region_merge' and table_name = 't1';
insert into region_merge.t1 values (-9223372036854775808),(0),(1),(9223372036854775807);
delete from region_merge.t1;
```
It is a TiCDC [integration test case](https://github.com/pingcap/tiflow/blob/master/tests/integration_tests/region_merge/run.sh) and has had frequent failures recently.
