How to reproduce
- Create a folder course element
- Subscribe for changes
- Open folder using WebDAV in MacOS
- Create some directories and upload files via WebDAV
- Trigger notifications for folder
=> NOK: MacOS meta-directories are listed as changes
While technically correct, most users don't understand what is happening as those meta directories are hidden when using the MacOS Finder or Windows Explorer. Meta directories should not be displayed in notifications, same as in the folder UI.
