Configurable product addtocart with restAPI not working as expected

[ghost]

Addtocart using same API work fine for simple product, but while adding configurable product with restAPI, it creates duplicate product entry in cart, it should ideally update the qty.
Using single store and quote id is also same.

Preconditions

1. Magento 2.2.3 (with sample data)

Steps to reproduce

1. Addtocart a configurable product from frontend.

2. Create quote id with customer token, (http://local.magento.com/rest/default/V1/carts/mine)

3. Addtocart same configurable product with rest API (http://local.magento.com/rest/default/V1/carts/mine/items)

Requets: { "cartItem": { "sku": "MJ12", "qty": 1, "quote_id": "11", "product_option": { "extension_attributes": { "configurable_item_options": [ { "option_id": "142", "option_value": "167" }, { "option_id": "93", "option_value": "49" } ] } } } }

Expected result

In cart there should be single product with two qty.

Actual result
