Possible bug in Debian 13 Trixie Alpha SDDM settings?

[Seldon]

While trying to change my wallpaper on the login screen, it appears the option to upload an image has disappeared. Is this new and the button is somewhere else, or am I missing a package, or is this a bug?

Definitely seems like a bug in Debian? It is present for me, and I have not noticed it being missing previously:

Operating System: KDE neon 6.3
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.14.0
Qt Version: 6.9.0
Kernel Version: 6.11.0-26-generic (64-bit)
Graphics Platform: Wayland

Is this a non-sudo/non-admin user account perhaps?

I am an administrator of this account, it seems.
