Did you get the error:"this broswer is no longer supported" when you load the html page?

If no, you can set DomStorageEnabled in webview handler.

   Microsoft.Maui.Handlers.WebViewHandler.Mapper.AppendToMapping("MyCustomizationwebview",(handler, view) =>  
           {  
   #if ANDROID  
     
               handler.PlatformView.Settings.JavaScriptEnabled = true;  
               handler.PlatformView.Settings.SetSupportMultipleWindows(true);  
               handler.PlatformView.Settings.DomStorageEnabled = true;  
               handler.PlatformView.Settings.AllowContentAccess = true;  
               handler.PlatformView.Settings.SetAppCacheEnabled(true);  
     
   #endif

Yes, you can copy it in your ContentPage or MauiProgramm.
I test this url in the Xamarin, but it is working, I think it is a bug about MAUI webview, please reported this issue in MAUI Github page.
If you want to show this page correctly, you can use await Launcher.OpenAsync("https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/webview"); instead.
