Bug report

PHPStan should treat anonymous classes as final.

Code snippet that reproduces the problem

interface Test {
	public static function create(): static;
}

$impl = new class implements Test {
	public static function create(): static {
		return new self();
	}
};

https://phpstan.org/r/9c7e89f4-0572-4bc8-b5ad-374c6f73071e

Method class@anonymous/tmp.php:7::create() should return static(class@anonymous/tmp.php:7) but returns class@anonymous/tmp.php:7.

Expected output

No issues reported by PHPStan.
