Thanks for this report! PR's are welcome to improve things if there is a way to do it without breaking backwards compat.

In the meantime, https://learn.microsoft.com/en-us/dotnet/desktop/wpf/whats-new/net90#thememode shows how to force light mode for a window. Hook into UIFactory.WindowHandler and set the mode you want and I am guessing you'll be good to go.

Or, override the UI for your app and set it up as you need. 😄
