Subject: [PATCH] [kcolorschememanager] Properly restore default palette
Currently when activating the default colorscheme we create a palette from the default KColorScheme
However that is different from the application's default palette
The former is effectively Breeze colors while the latter is fetched from the platformtheme
By setting a default-constructed QPalette we tell Qt to load the default palette
BUG: 447029
