Description:
On identical table data, a `SELECT` with `WHERE (t0.c0) IN (IF(...))` should return **0** rows, but MySQL 9.6.0 returns **1** row.

How to repeat:
DROP TABLE IF EXISTS `t0`;

CREATE TABLE `t0` (
  `c0` int DEFAULT NULL,
  KEY `i0` (`c0`)
);

INSERT INTO `t0` (`c0`) VALUES (1);

SELECT t0.c0 AS ref0 FROM t0 WHERE (t0.c0) IN (IF(1964541864, 0.5974530509260936, -1153166958));
