StructLevel.Parent() not return real parent

[Torwang1]

Package version eg. v9, v10:

V10

Issue, Question or Enhancement:

validator.StructLevel.Parent() not return real parent, when the struct is nested.

type (
	// User ...
	User struct {
		Name    string
		Address Address `validate:"structonly"`
	}

	// Address ...
	Address struct {
		Street string
	}
)

validator.StructLevel.Parent() on nested Address:
expect: User
but: Address

Code sample, to showcase or reproduce:

package main

import (
	"context"
	"fmt"
	"reflect"

	"github.com/go-playground/validator/v10"
)

func init() {
	validate = validator.New()

	validate.RegisterStructValidationCtx(AddressValidate, Address{})
}

var validate *validator.Validate

type (
	// User ...
	User struct {
		Name    string
		Address Address `validate:"structonly"`
	}

	// Address ...
	Address struct {
		Street string
	}
)

// AddressValidate ...
func AddressValidate(ctx context.Context, sl validator.StructLevel) {
	parent := sl.Parent().Type()
	fmt.Println(parent)

	real := reflect.TypeOf(Address{})
	expected := reflect.TypeOf(User{})

	switch parent {
	case real: // Address is nested in User. not the first call to validateStruct
		fmt.Println("why Address Parent not User")
	case expected:
		fmt.Println("expecte that Parent is User")
	}
}

func main() {
	user := new(User)

	validate.Struct(user)
}
