Category Manager: ACL inheritance is (still) not working (or only a view issue in the new GXL ACL viewer)

I imported the online demo which has some pre-packaged categories. Then I imported the geneva counties import file for categories. Finally I added some steven user on this newly imported "Plan de classement".

It looks like the default users group assigned on the root is not inherited on sub categories. When adding a steven user (read only) on the "Plan de classement", such a user does not inherit read permissions on the sub-categories.

Clearly speaking the ACL management of the category tree should be exactly the same one as the Jahia content tree. In the long run all these tree will merge into a unique federated JCR tree. So more close we are manaing all our "trees" (category tree, file tree or content tree) more easy the migration will be.
