UPDATE on RocksDB table with unique constraint does not work

Details

    Description

      CREATE TABLE t1 (a INT, b CHAR(8), UNIQUE INDEX(a)) ENGINE=RocksDB;
      		 
      INSERT INTO t1 (a,b) VALUES (1,'foo'),(2,'bar');
      		 
      UPDATE t1 SET a=a+100;
      		 
      SELECT * FROM t1;

      Actual result

      		 
      MariaDB [test]> SELECT * FROM t1;
      		 
      +------+------+
      		 
      | a    | b    |
      		 
      +------+------+
      		 
      |  101 | foo  |
      		 
      |    2 | bar  |
      		 
      +------+------+
      		 
      2 rows in set (0.00 sec)

      Expected result

      		 
      MariaDB [test]> SELECT * FROM t1;
      		 
      +------+------+
      		 
      | a    | b    |
      		 
      +------+------+
      		 
      |  101 | foo  |
      		 
      |  102 | bar  |
      		 
      +------+------+
      		 
      2 rows in set (0.00 sec)

      It is a recent regression, apparently from the last merge or post-merge changes, I didn't search for the exact commit.
