Thank you for the report!
I repeated on 10.4-10.8, with InnoDB, not reproducible with myisam.
10.2,10.3 do not except such syntax (HAVING a LIKE a).
no visible effect on non-debug build.

--source include/have_innodb.inc

CREATE TABLE t1 (a TEXT(60) NOT NULL ) engine=innodb;

INSERT INTO t1 VALUES ('1'),('0');

SELECT DISTINCT * FROM t1 WHERE "" IN (SELECT 'x' LIKE a HAVING a LIKE a) ;
