      Description

      A problem that supposedly was fixed (MDEV-22745, MDEV-20439, MDEV-22723, MDEV-19983) seems to still exist.
      In this case the 10.4 node is replicating changes but still reporting:

      wsrep_cluster_size as 0
      wsrep_cluster_conf_id 18446744073709551615

      The versions are:

      On existing 2 nodes:

      galera-25.3.35-1.el7.centos.x86_64
      MariaDB-common-10.3.35-1.el7.centos.x86_64
      MariaDB-server-10.3.35-1.el7.centos.x86_64
      MariaDB-compat-10.3.35-1.el7.centos.x86_64
      MariaDB-client-10.3.35-1.el7.centos.x86_64
      MariaDB-backup-10.3.35-1.el7.centos.x86_64
      MariaDB-shared-10.3.35-1.el7.centos.x86_64

      On upgraded node:
      galera-4-26.4.11-1.el7.centos.x86_64
      MariaDB-compat-10.4.25-1.el7.centos.x86_64
      MariaDB-server-10.4.25-1.el7.centos.x86_64
      MariaDB-common-10.4.25-1.el7.centos.x86_64
      MariaDB-backup-10.4.25-1.el7.centos.x86_64
      MariaDB-client-10.4.25-1.el7.centos.x86_64
      MariaDB-shared-10.4.25-1.el7.centos.x86_64

      Tried a workaround also, starting with wsrep_on=OFF and turning it on afterwards, no luck (see attached)
