Auto dark/light theme

[cbrnr]

Manually switching themes has always been possible, but does auto-switching (depending on the system settings) also work? It seems like it should given the following section in config.toml:

    ######################################
    # Dark Mode

    enableDarkMode = true

    defaultTheme = "light"
    # Note: light or dark

    hideThemeToggle = false
    hideThemeToggleInHome = false
    # Note: If dark mode is enabled and
    #       theme toggle is hidden, your
    #       readers may still read your
    #       blog in dark mode if the
    #       reader’s system is set to dark
    #       mode. Similarly, if dark mode
    #       is enabled and is set to the
    #       default theme, your readers
    #       may still read your blog in
    #       light mode, even if you have
    #       hidden the theme toggle.
    #       Unless you enable the following
    #       option.

    overrideSystemPreferences = false

However, no matter what I set here the website does not adapt to the system theme (I'm on macOS). Is auto-switching possible somehow?
