ALTER..INPLACE does not work for BINARY data type

DROP TABLE IF EXISTS t1;

CREATE TABLE t1 (a BINARY(10));

ALTER TABLE t1 MODIFY a BINARY(10), ALGORITHM=INPLACE;

returns

ERROR 1846 (0A000): ALGORITHM=INPLACE is not supported. Reason: Cannot change column type INPLACE. Try ALGORITHM=COPY.

The same error happens for BLOB:

DROP TABLE IF EXISTS t1;

CREATE TABLE t1 (a BLOB);

ALTER TABLE t1 MODIFY a BLOB, ALGORITHM=INPLACE;

The same problem happens for GEOMETRY:

DROP TABLE IF EXISTS t1;

CREATE TABLE t1 (a GEOMETRY);

ALTER TABLE t1 MODIFY a GEOMETRY, ALGORITHM=INPLACE;

Note, it does work fine for VARBINARY:

DROP TABLE IF EXISTS t1; CREATE TABLE t1 (a VARBINARY(10));

ALTER TABLE t1 MODIFY a VARBINARY(10), ALGORITHM=INPLACE;
