LONGTEXT column with collation doesn't sort

Creating a table with a LONGTEXT column with COLLATE doesn't sort properly.
Using TEXT or dropping COLLATE working as expected. Also working on 10.4.

CREATE TABLE t (

 c LONGTEXT COLLATE utf8mb4_swedish_ci

);

INSERT INTO t (c) VALUES ('A'),('Z'),('B'),('Y');

SELECT * FROM t ORDER BY c ASC;

Result:
A,Z,B,Y

Expected:
A,B,Y,Z
