Assertion `(node->state == 5) || (node->state == 6)' failed in row_upd_sec_step upon DELETE after UPDATE failed due to FK violation

      Description

      Note: the test case involves versioning, so I can't check whether 10.2 is affected. It's quite possible that versioning is not necessary, and some other table structure would suffice, but I don't know what it should be.

      --source include/have_innodb.inc
       
      CREATE TABLE t1 (f1 INT, KEY(f1)) ENGINE=InnoDB;
      CREATE TABLE t2 (f2 INT, FOREIGN KEY (f2) REFERENCES t1 (f1)) ENGINE=InnoDB WITH SYSTEM VERSIONING;
       
      --connect (con1,localhost,root,,test)
      SET FOREIGN_KEY_CHECKS= OFF;
      INSERT IGNORE INTO t2 VALUES (1);
       
      --connection default
      --error ER_NO_REFERENCED_ROW_2
      UPDATE t2 SET f2= 2;
      DELETE FROM t2;
       
      # Cleanup
      --disconnect con1
      --connection default
      DROP TABLE t2, t1;
