UI Scaling in SDDM no longer works after KDE Plasma 6 upgrade

I have a 2880x1800, 90Hz, 14 inch screen, so a 200% scaling is required for comfortable use. While this is a minor issue, I would rather have it working.

No tinkering needed. A single line in the only configuration file works fine with Plasma:

erlangen:~ # cat /etc/sddm.conf
[General]
GreeterEnvironment=QT_SCREEN_SCALE_FACTORS=2,QT_FONT_DPI=192
erlangen:~ #
