BUG: AdMob SDK (24.0.0+) prevents Dynamic Colors from updating on Android 15+

[Sam Lu]

Integrating and displaying a banner ad using the AdMob SDK appears to break the
functionality of Android's dynamic colors feature on devices running Android 15
and Android 16 beta 3. The app's theme colors, which should update based on
the user's wallpaper selection, become static after an AdMob ad is shown.

• OS: Android 15, Android 16 beta 3
• Devices: Pixel 6 Pro, Pixel 8 Pro (observed on)
• AdMob SDK Version: com.google.android.gms:play-services-ads:24.0.0 or greater
• Relevant Android Feature: Dynamic Colors (https://developer.android.com/develop/ui/views/theming/dynamic-colors)

Issue Demonstration:

• This video (https://www.youtube.com/shorts/rkgy7ynbZ4s) shows the app's colors correctly changing based on the user's selected wallpaper color by disabling AdMob ads.  
• This video (https://www.youtube.com/shorts/LC5Pay8ZQdU) shows the app's colors failing to change when the user selects a different wallpaper color after integrating and displaying AdMob ads.

 
How to Reproduce:

1. Download and open the attached dynamic_colors_fail-enable_admob.zip sample code.
2. Navigate to MainActivity.kt.
3. Change the ENABLE_AD variable on line 28 to true to enable ads or false to disable them and observe the difference in dynamic color behavior.

Code Snippet:
CoroutineScope(Dispatchers.IO).launch {
    // true -> dynamic colors does not work
    val ENABLE_AD = true

    if (ENABLE_AD) {
        MobileAds.initialize(this@MainActivity) {
            runOnUiThread {
                loadBanner()
            }
        }
    }
}

This is not connected to AdMob but to WebView. 

If WebView is used then dynamic colors stop working.
