When connecting to a remote server via sftp:daniel@192.168.122.1 for example, it is impossible to reach the root of the filesystem (`/` with boot, etc, home, opt... not `/root`) of the server. By default, dolphin will take me to /home/daniel and show `sftp : 192.168.122.1 > home > daniel` in the location bar. When I click on the arrow between `sftp : 192.168.122.1` and `home` I can see a drop down of the contents in the root of the filesystem: boot, etc, home... When I click on the `home` button it takes to /home as exepcted. When I click on `sftp : 192.168.122.1` it takes me back to `/home/daniel`, but now the location bar just says `sftp : 192.168.122.1`. There is no way to reach / without symlinking it in my home folder `ln -s / /home/daniel/rootdir`. This can be reproduced on a Fedora 42 KDE live cd and trying to connect to the host. According to the discussion thread, it looks like this also effects the fish protocol: https://discuss.kde.org/t/sftp-root-directory/38039 .
