A configurable product with variants configured around 2 attributes: first is visual swatch with 5 options, second is text swatch with 3 options, also has required customizable option.
A simple product associated with 2 selected options that I want to add to the cart also has a tier price for qty 5. I added 2 exactly the same configurable variants in quantity of 5 each with different customizable options.
My request for the second item (exactly the same except customizable option value)

mutation {
  addConfigurableProductsToCart(
    input: {
      cart_id: "pTJWGSAzx9mGs8Q3WT7HgE81O2MCO02e"
      cart_items: {
        data: {
          quantity: 5
          sku: "configurable-product-1-white-wholesale@us-mobiles.cn"
        }
        parent_sku: "configurable-product-1"
        customizable_options: {
          id: 1
          value_string: "blah-blah"
        }
      }
    }
  ) {
    cart {
      email
      items {
        id
        quantity
      }
    }
  }
}

Response

{
  "data": {
    "addConfigurableProductsToCart": {
      "cart": {
        "email": "John.Doe@example.com",
        "items": [
          {
            "id": "23",
            "quantity": 5
          },
          {
            "id": "25",
            "quantity": 5
          }
        ]
      }
    }
  }
}

When I try to update the quantity for any of the items I have the following situation:

Request

        cart_item_id: 23
        quantity: 1
      }
    }

        quantity: 1
      }
    }
  ) {
    cart {
      items {
        id
        quantity
      }
    }
  }
}

Response

{
  "data": {
    "updateCartItems": {
      "cart": {
        "items": [
          {

          },
          {
            "id": "25",
            "quantity": 1
          }
        ]
      }
    }
  }
}

Expected result

Actual result

The response fools me
