Seems to be an issue on Mac too. Automatic defaults to Dark Mode. prefers-color-scheme returns the wrong theme color (Dark instead of Light), i.e. by checking with:

if (window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches) {
  console.log('User prefers dark mode');
} else {
  console.log('User prefers light mode');
}
