Rest API attribute set updating not working as expected

[NotAndD]

Preconditions

1. Install Magento 2.1.3 with sample data.
2. Set up Rest integration.

Steps to reproduce

1. Try to update an attribute set from /V1/products/attribute-sets/{attributeSetId} with a PUT request, inserting in the body ONLY the not-optional parameters (as explained in the documentation).

{
"attribute_set": {
"attribute_set_name":"Updated Name",
"sort_order":0 }
}

and with an existing attribute set id as url parameter

Expected result

1. The attribute set with given attribute set id gets updated with the new name

Actual result

1. It doesn't get updated and magento answer with
   {"message":"Provided Attribute set non product Attribute set."}

Why

1. Field entity_type_id is NOT optional in the PUT request, differently from what the documentation says.
2. If field attribute_set_id is only in the url parameter and NOT in the body, instead of updating the attribute set, a new attribute set with the given fields is created.
3. Only if both fields attribute_set_id and entity_type_id are given in the body, the request is succesful and the attribute set with the given id in the url parameter is updated.

use this api
/V1/eav/attribute-sets/:attributeSetId
with payload of
{
"attribute_set": {
"attribute_id" : 10, // whatever attributesetid u have..
"attribute_set_name":"Updated Name",
"sort_order":0 }
}

I believe there is still an issue.

$result = $attributeSet->getEntityTypeId() === $productEntityId; is returning false because:

$productEntityId = $this->eavConfig->getEntityType(\Magento\Catalog\Model\Product::ENTITY)->getId(); returns a string while

$attributeSet->getEntityTypeId() is an integer and the type comparison fails.
