Validation "required" field in non required

• PHP Version: 7.4.7
• Database Driver & Version:

Description:

If required field is in NON required field and non required field is ommited, validation should pass

Steps To Reproduce:

$data = [
    'field' => [
        // Should be valid
        [
            'non_required' => [ // << This field is not required by rules
                'required_field' => true, // but this it is
            ],
        ],
        // Should be valid
        [],
    ],
];
$rules = [
    'field.*.non_required.required_field' => 'required',
];

// Expecting: if "non_required" is present, than "required_field" is required
// so both array items should be valid by rules, but it is not.
$this->assertFalse(Validator::make($data, $rules)->fails());

This is not a bug in existing behavior - this is simply just not supported.
