What is the current behavior?
Currently, WndProc in SystemThemeWatcher only listens to
WM_DWMCOLORIZATIONCOLORCHANGED,WM_THEMECHANGEDandWM_SYSCOLORCHANGEmessages. These don't fire when theme changes happen through Windows Settings > Personalization > Colors > Choose your mode (Light/Dark).The docs imply that
ApplicationThemeManager.Changedtriggers from "automatic updates", which I believe should include Windows theme changes as well.Issue Number: #1656
What is the new behavior?
