Table from older version requires table rebuild when adding column to table with multi-column index

Details

    Description

      How to reproduce:

      On a 10.4 server instance do:

      CREATE TABLE t1 (
      		 
        id int not null primary key,
      		 
        msg varchar(10),
      		 
        index(id, msg)
      		 
      ) ENGINE=InnoDB ROW_FORMAT=DYNAMIC;

      Then upgrade to 10.5 and try to instant-add a column:

      alter table t1 add column i int, algorithm=instant;

      This fails with: 

      ERROR 1845 (0A000): ALGORITHM=INSTANT is not supported for this operation. Try ALGORITHM=INPLACE

      Same table created on 10.5 right away allows to add the column in instant mode just fine.
