Group folders ACL not working for user permissions inheritance

[iwrbr]

Hi all,

Nextcloud: 20.0.6
Group folders: 8.2.0

For a group folder hierarchy, permissions granted for user groups are inherited by subsequent subfolders and files, but permissions granted for particular users are not inherited in the same manner.

I.E:
For some folder (called "Archive") in the group folder hierarchy, if I grant only read permission for group "USERS" (which the user "John" is part of) and grant all rights for user "John" (there are more users in the "USERS" group than "John" and I want only "John" to modify this particular folder), then "John" will have all rights in the "Archive" folder.
Then I create subfolder "2020" inside "Archive" folder (using the admin user, so there will be /Archive/2020/) without touching permissions for this folder.
Then "John" can see the folder "2020" and it's content (granted by both permission for group "USERS" and by permission for user "John"), but cannot write/delete/create into it, even if the permissions "John" sees for folder "2020" are "inherited" write/delete/create.

This means the rights of the group "USERS" overwrites the rights of the user "John" for the subsequest subfolders and files

I believe this is a bug

I think this is a duplicate of #1212 and/or #598.
@iwrbr Can you please check these issues and the PR #1654 and see if this covers your issue? Thanks!
