Bug#921552: sddm-theme-debian-maui: Maui decorations are missing after recent upgrades

[Steven De Herdt]

Control: reassign -1 desktop-base 10.0.0
Control: severity -1 minor
Control: merge -1 921678

This is actually a bug with the new "futurePrototype" theme in
desktop-base, to be fixed in an imminent upload.

Kind regards
-Steven
