From my perspective it's a bug, but there is a workaround that reliably works for me. You have to setup a directory that is accessible to user sddm (I use my home dir, since its rwx-rxr-x) and put there a file called <username>.face.icon (in my case rocky.face.icon), which also needs to be readble by user sddm (so rw-r--r--). The you have to modify the file /etc/sddm.conf and add there something like this:
FacesDir parameter is the one to be added... Login screen will then show all avatar for all users that have their pictures in the specified directory.
Code:
[Theme]
Current=breeze
CursorTheme=breeze_cursors
FacesDir=/home/rocky/
