STEPS TO REPRODUCE
1. set Breeze global theme
2. install Layan global theme from KDE Store
3. apply Layan global theme
color scheme of Layan global theme was not applied to header bar of System Settings.
I can fix this applying another dark color scheme in Colors KCM and then applying
Layan color scheme again.
Global Theme KCM should apply color scheme included in Layan global theme correctly
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.22.80
KDE Frameworks Version: 5.83.0
Qt Version: 5.15.2
Graphics Platform: Wayland
X11 too? Or just Wayland?
Can reproduce on both X11 and Wayland with the Layan theme.
