Wrong query result due to Table Elimination hitting unique_col IS NULL condition

SELECT t1.c1 FROM t1 LEFT JOIN t0 ON (t0.c0 IS NULL);

SELECT * FROM t1 LEFT JOIN t0 ON (t0.c0 IS NULL);

sudo docker run -it -p 3307:3306 -e MARIADB_ROOT_PASSWORD=root mariadb:latest

CREATE TABLE t0(c0 FLOAT);

CREATE TABLE t1(c1 FLOAT);

INSERT INTO t0 VALUES (NULL), (NULL);

INSERT INTO t1 VALUES (1.0);

CREATE UNIQUE INDEX i0 USING BTREE ON t0(c0);

SELECT t1.c1 FROM t1 LEFT JOIN t0 ON (t0.c0 IS NULL);
