Assertion `buf == table->record[0]' fails in virtual int ha_rocksdb::delete_row(const uchar*)

[elenst]

Test case

CREATE TABLE t1 (pk INT PRIMARY KEY, f1 INT) ENGINE=RocksDB;
CREATE TABLE t2 (pk INT PRIMARY KEY, f1 INT) ENGINE=RocksDB;

CREATE TRIGGER tr AFTER DELETE ON t1 FOR EACH ROW DELETE FROM t2 WHERE pk = old.pk; 

INSERT INTO t1 VALUES (1,1);
REPLACE INTO t1 VALUES (1,2); 

# Cleanup

SELECT * FROM t1;
DROP TABLE t1, t2;
