Child categories using the same name are grouped as one in category module

[joomlafun]

Steps to reproduce the issue

1° Create a joomla category module
2° In filtering option; select "inclusive" with 2 child categories having the same name.

Expected result

The module should show 2 category groups of articles.

Actual result

The module shows one category group with all articles of both categories in it.

System information (as much as possible)

Joomla! 3.9.6 ; php 7.3

Additional comments

It would be great to have the module to show the parent categories as well to differenciate the 2 child categories which have the same name.

Solving this would require a big change in data passed to the layout. So I don't think we can fix this in J3.
