Menu blocks app switching
When the Shortwave menu is visible it effectively blocks all other apps including Alt+Tab switching and Meta key menu. Only keys relevant to navigating the menu are accepted. I’d expect it to be modal to Shortwave only, not the whole OS.
Manjaro + Cinnamon 5.0.7 Shortwave: both AUR package (1:2.0.1-1) and Flatpak (2.0.1)
