SUMMARY STEPS TO REPRODUCE 1. Set a Global Theme with Plasma Style included (e.g. Sweet); 2. Set a Plasma Style that doesn't match the theme you set before (e.g. if you set Sweet theme, set Breeze Dark Plasma Style); 3. Reboot or re-login. OBSERVED RESULT Plasma Style reverts back to the one from the Global Theme. EXPECTED RESULT Plasma Style stays on what it was explicitly set.
