Dark theme does not apply at all
I am running the recent master version from flatpak on my Manjaro with Cinnamon.
In Cinnamon I use a dark theme. If I start Pitivi, it comes up light.
I installled the dark theme in flatpak - still light.
I overwrote the theme folder in flatpak - still light.
The switch in Preferences for dark theme seems to have no effect at all.
