MDEV-25758 InnoDB spatial indexes miss large geometry fields after MDEV-25459

Browse Source 
InnoDB should calculate the MBR for the first field of
spatial index and do the comparison with the clustered
index field MBR. Due to MDEV-25459 refactoring, InnoDB
calculate the length of the first field and fails with
too long column error.
