Request category with products stop showing products in nested categories since v0.11.2

[imdimasan]

Describe the bug
Request a category with products nodes returns only first-level category products. This was changed in v0.12.0. I can't find any solution to retrieve all products in nested categories since v0.12.0.

To Reproduce
Steps to reproduce the behavior:

1. Install both versions 0.11.2 and 0.12.0
2. Activate 0.11.2
3. Make a request:
   query GetCategory { productCategories(where: {slug: "komfort"}) { nodes { id name uri products(first: 99) { nodes { ... on VariableProduct { id name variations { nodes { id name } } } ... on SimpleProduct { id name } } } } } }
4. Deactivate v0.11.2
5. Activate v0.12.0
6. Make a request with the same query

Expected behavior
As WooCommerce supports categories hierarchy and can be changed in Appearance - > WooCommerce -> Categories / Products I'm expecting see the same result. I mean, If I have hierarchy such as:

• Electronics (0)
  -- Smartphones (0)
  --- Apple (18)
  --- Samsung (5)

So when I request category "Electronics" with products query, I want to see all products in child categories (Apple and Samsung).

It works as expected in v.0.11.2, then 0.12.0 not.
