Created attachment 118334 [details] screenshot plasma-browser-integration with Opera browser is failing on neon dev unstable. Plasma shows a notification with barely visible icon while breeze dark theme is used. See the screenshot. Operating System: KDE neon Developer Edition KDE Plasma Version: 5.15.80 KDE Frameworks Version: 5.56.0 Qt Version: 5.12.0
That notification is removed from the upcoming version. The browser action popup used instead supports dark mode, at least on Firefox.
