Screen Locking KCM (with D23184)

When a QQuickWidget is placed inside a QTabBar, the background color of the QtQuick parts differ slightly from the background color of the area inside the QTabWidget. This appears to be because the Breeze theme slightly lightens the background color of the TabWidget's frame, but this does not happen for QtQuick components.

Perhaps we could detect when a QtQuick scene is placed inside a QtQuickWidget that's inside a QTabBar, and then perform the same background color adjustment. Basically we need to do this: https://cgit.kde.org/sddm-kcm.git/tree/src/qml/main.qml#n27

...but only conditionally, when it's inside a QTabBar.
