Nested groupfolder sync broken with Nextcloud desktop client

[Abraxas0]

Steps to reproduce

1. Create a group folder (e.g. "Parent Directory")
2. Create a sub group folder (e.g. "Parent Directory/Sub Directory")
3. Create a plain text file at parent directory (-> will be synced to server and all Windows clients)
4. Create a plain text file at sub directory (-> will be synced to server and all Windows clients)
5. Change the plain text file at parent directory (-> will be synced to server and all Windows clients)
6. Change the plain text file at sub directory (-> will be synced to server, but not to any Windows client)
7. Change the plain text file at parent directory again or make any change to the parent directory (-> will be synced to server and all pending changes from step 6 will now be synced to all Windows clients too)

This behaviour affects only nested group folders, not plain sub directories in a group folder.

Expected behaviour

All changes of files pushed to or made on the server (create, modify, delete of a file) inside nested group folders should be pushed to all clients.

Actual behaviour

Changes of files pushed to or made on the server (create, modify, delete of a file) inside nested group folders are pushed to Windows clients only if any change have been made to at least one file inside the root group folder.

Same Problem at my device
No poll for subfolders within the groupfolders.
No error within desktop client logs and server-logs.

Server Version: 22.2.3
Desktop Client Version: 3.3.6
Windows 10
No Firewall between desktop client and nextcloud server.

The behavior exists for a long time and many versions. Only ignored it and got the changed new and chaned files by disabling and enabling the sync for the folder.

Additional info:

I've made some tests with a 3rd level of group folder right now. It seems that changes to files in the 1st and 3rd level trigger sync, but not on 2nd level.

I see the same issue on my configuration

Groupfolder : 13.1.1
Desktop Client Version: 3.5.4 (Linux Ubuntu 20.04) and 3.7.3 (Windows 10)

I understand that we can use groupfolders with the sync client only if we don't use subfolders.
We can create subfolders but not in the GroupFolders application, only by users in the shared folder
