Redundant table alter fails when fixed column stored externally

Details

    Description

      Looks similar to MDEV-27858 however this bug remains post-patch. It is however not caused by the patch, as the bug can be found in builds from late January 2022.

      SET GLOBAL innodb_default_row_format=0;
      		 
      SET sql_mode='',unique_checks=0,foreign_key_checks=0;
      		 
      CREATE TABLE t (pk INT,c CHAR(255),c2 CHAR(255),c3 CHAR(255),c4 CHAR(255),c5 CHAR(255),c6 CHAR(255),c7 CHAR(255),c8 CHAR(255),PRIMARY KEY(pk)) ENGINE=InnoDB CHARACTER SET utf32;
      		 
      INSERT INTO t(c) VALUES (10);

      Leads to:
