ACSD-50794: Cannot remove gift wrapping from customer order via GraphQL

Create a customer from the frontend.

Create a simple product.

Enable Gift Messages by going to Stores > Configuration > Sales > Gift Options and set Allow Gift Messages = Yes.

Create Gift Wrapping by going to Stores > Other Settings > Gift Wrapping.

Get customer token.

Create an empty cart, customerCart.

• Add products to the cart: addProductsToCart mutation
• Set billing address: setBillingAddressOnCart mutation
• Set shipping address: setShippingAddressesOnCart mutation
• Set shipping method: setShippingMethodsOnCart mutation (flatrate)
• Set payment method: setPaymentMethodOnCart mutation (checkmo)

Now check the gift wrapping Uid with this cart query:

{
  cart(cart_id: "{{CART_ID}}") {
    available_gift_wrappings{
        uid
    }
}
}

Set gift wrap using setGiftOptionsOnCart.

Check the cart: cart query.

Unset gift wrap using setGiftOptionsOnCart (set value to null).

Again, check the cart: cart query.

Place order: placeOrder mutation.

Run customer query: customer.

query {
  customer {
    firstname
    middlename
    lastname
    suffix
    email
    orders {
        items {
            order_date
            gift_wrapping {
                design
                uid
            }
        }
    }
    addresses {
      firstname
      middlename
      lastname
      street
      city
      region {
        region_code
        region
      }
      postcode
      country_code
      telephone
    }
  }
}
