usr-share-sddm-themes.mount fails because it is not empty, mounting anyway

[Renner0E]

Describe the bug

I run my own custom image FROM bazzite.
I did not customize /usr/share/sddm/themes in any way.

ls /usr/share/sddm/themes
01-breeze-fedora  breeze

What did you expect to happen?

systemd service doesn't fail. workaround for sddm.... works
