Splashscreen and Dark/Light theme behavior changed on Android

[AlleSchonWeg]

Description

Hi,
something changed with Splashscreens and dark/light theming. I don't know when but i'm sure i had this working in my app. I use the Xamarin.AndroidX.Core.SplashScreen 1.0.1.12 nuget, because i need to display the splash a little bit longer and different colors for dark/light theme.

What i did:
In my csproj file i removed the MauiSplashScreen section.
In Platforms/Android/Resources i created values and values-night folder with styles.xml and colors.xml
In MainActivity.cs i set:
[Activity(Theme = "@style/Theme.Splash", MainLauncher = true, LaunchMode = LaunchMode.SingleTop, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation | ConfigChanges.UiMode | ConfigChanges.ScreenLayout | ConfigChanges.SmallestScreenSize | ConfigChanges.Density)]
In MauiProgram.cs i call installSplashScreen:

                                .UseMauiApp<App>()
                                .ConfigureLifecycleEvents(events =>
                                {
#if ANDROID
                                    events.AddAndroid(android => android
                                    .OnCreate((activity, bundle) =>
                                    {
                                        AndroidX.Core.SplashScreen.SplashScreen.InstallSplashScreen(activity);
                                    }));
#endif
                                })

If i run the app the colors in the splashscreen are correct. Depending what i set in styles.xml/colors.xml and if device is in dark/light mode.
For example my styles.xml in values-night for dark mode:

<?xml version="1.0" encoding="utf-8" ?>
<resources>
  <style name="Test.Theme" parent="Maui.MainTheme.NoActionBar">
    <item name="android:windowLightNavigationBar">false</item>
    <item name="android:windowLightStatusBar">false</item>
    <item name="android:statusBarColor">@color/appColor</item>
    <item name="android:navigationBarColor">@color/appColor</item>
    <item name="android:windowBackground">@color/background</item>
    <item name="android:windowIsTranslucent">false</item>
    <item name="android:windowTranslucentNavigation">false</item>
    <item name="android:windowTranslucentStatus">false</item>

  </style>
  <style name="Theme.Splash" parent="Theme.SplashScreen">
    <item name="windowSplashScreenBackground">@color/background</item>
    <item name="windowSplashScreenAnimationDuration">200</item>
    <item name="postSplashScreenTheme">@style/Test.Theme</item>
    <item name="android:windowLightNavigationBar">false</item>
    <item name="android:windowLightStatusBar">false</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
    <item name="android:navigationBarColor">@android:color/transparent</item>
  </style>
</resources>

And my colors.xml in values-night:

<resources>
  <color name="colorPrimary">#0bbd8b</color>
  <color name="colorPrimaryDark">#0bbd8b</color>
  <color name="colorAccent">#0bbd8b</color>
  <color name="appColor">#0bbd8b</color>
  <color name="background">#0bbd8b</color>
</resources>

$${\color{#0bbd8b}0bbd8b \space is \space this \space color}$$

This is the SplashScreen in dark-mode:

The colors are correct. Butt problem is, when i switch the device from dark to light theme via system settings and the app is running the colors for statusBarColor and navigationBarColor are not changed to the values i set in Android/Resources/values/colors.xml. I have to restart the app to change the colors. Same happens if i change from light to dark mode.
The screenshot shows after changing from dark to light. StatusBar and NavigationBar are have still the dark theme colors:

I'm sure that this worked some time ago.

Steps to Reproduce

Open sample app
Change device theme
Go back to app
Statusbar and Navigationbar should changed the colors.
