Unexpected -Wconstant-logical-operand warning when compiled with c2x/gnu2x

#include <stdio.h>

int main() {
	if ((64 > 32) && (32 < 64))

	return 0;

Build with -std=c17 or -std=gnu17 and below prints no error, but this emits warnings when built with c2x or gnu2x. Is this expected behaviour that reflects some changes in C23 or a bug?

This looks related to: #64356

This is duplicate of #64356, though it still remains in clang 17.0.6 (Darwin amd64/aarch64 on macOS Sonoma, installed through Homebrew) Is this issue resolved in Clang 18?
