Each + Nested doesn't work for collection of objects

[marcinskubala]

What steps will reproduce the problem?

class A {
    #[Required]
    public $id;
}
class B {
    #[Each([
        new Nested()
    ])]
    public $array_of_a;
}

$a = new A();
$b = new B();
$b->array_of_a = [$a];

$result = $validator->validate($b);
echo $result->getErrorMessages()[0];

What is the expected result?

"Id cannot be blank."

What do you get instead?

"Nested rule without rules requires array_of_a to be an object. array given."
