Additional context

This bug was reported by a user of EcoPaste, so it's not just my computer!

Originally I was trying to achieve this by doing the following, but it was also problematic!

useAsyncEffect(async () => {
        const appWindow = getCurrentWebviewWindow();

        let isDark = globalStore.appearance.theme === "dark";

        if (globalStore.appearance.theme === "auto") {
            isDark = (await appWindow.theme()) === "dark"; // Gets the theme color of the window
            // or
            isDark = window.matchMedia("(prefers-color-scheme: dark)").matches; // It is also the theme color of the window, not the system theme color.
        }

        appWindow.setTheme(isDark ? "dark" : "light");

        globalStore.appearance.isDark = isDark;
}, [globalStore.appearance.theme]);

// If the value of `appWindow.setTheme` is not null or undefined, a change in the system theme will not be triggered.
appWindow.onThemeChanged(async ({ payload }) => {
    if (globalStore.appearance.theme !== "auto") return;

    globalStore.appearance.isDark = payload === "dark";
});
