mutation {
  updateProductsInWishlist(
    wishlistId: "1",
    wishlistItems: [
      {
        wishlist_item_id: "1",
        quantity: 2,
        description: ""
      }

    wishlist {
      id
      items {
        id
        description
        product { name }
      }
    }
  }
}`

### Expected result

The description (comment) on wishlist item 1 should be cleared (i.e. set to null or an empty string) in the database, and the GraphQL response should show either:

"description": null or "description": ""

### Actual result

The GraphQL response still returns the old, non-empty description.
Reviewing the database, the wishlist_item.comment column remains unchanged.

{
"data": {
 "updateProductsInWishlist": {
   "wishlist": {
     "items": [
       {
         "id": "1",
         "description": "My original comment",
         "product": {
           "name": "24-MB01"
         }
       }
     ]
   }
 }
}
}
