      Description

      Possibly connected with MDEV-27240 but versions are different, and issue does not reproduce with InnoDB.

      INSTALL PLUGIN spider SONAME 'ha_spider.so';
      CREATE TABLE t0 (s0 INT) ENGINE=SPIDER;
      FLUSH TABLE t0 WITH READ LOCK;
      BEGIN WORK;
      

      Leads to:
