[regression/8.0.0-preview.4.8333] Borderless Entry Handler Not Working in .NET MAUI 8.0

[mistrypragnesh40]

Description

Here is the code.

        Microsoft.Maui.Handlers.EntryHandler.Mapper.AppendToMapping(nameof(CustomEntry), (handler, view) =>
            {
#if ANDROID
                handler.PlatformView.Background = null;
                handler.PlatformView.SetBackgroundColor(Android.Graphics.Color.Transparent);
#elif IOS
            handler.PlatformView.BackgroundColor = UIKit.UIColor.Clear;
            handler.PlatformView.Layer.BorderWidth = 0;
            handler.PlatformView.BorderStyle = UIKit.UITextBorderStyle.None;
#endif
            });```
            
            

### Steps to Reproduce

1. Create CustomEntry Class that inherit Entry Class.
2. Use That Handler in UI.
3. Add Handler Mapping on App.xaml.cs

    Microsoft.Maui.Handlers.EntryHandler.Mapper.AppendToMapping(nameof(CustomEntry), (handler, view) =>
        {

#if ANDROID
handler.PlatformView.Background = null;
handler.PlatformView.SetBackgroundColor(Android.Graphics.Color.Transparent);
#elif IOS
handler.PlatformView.BackgroundColor = UIKit.UIColor.Clear;
handler.PlatformView.Layer.BorderWidth = 0;
handler.PlatformView.BorderStyle = UIKit.UITextBorderStyle.None;
#endif
});```

[XamlTest]

Verified this on Visual Studio Enterprise 17.8.0 Preview 2.0(8.0.0-rc.1.23419.4). Repro on Windows 11 and Android 13.0-API33, not repro on iOS 16.4 with below Project:
BorderlessEntryDemo.zip

Windows:

Android:

iOS:

Confirmed that this regressed on Android between 8.0.0-preview.3.8149 and 8.0.0-preview.4.8333. #12227 seems sus, though that doesn't explain the Windows issue.

I've tested the fix (pullrequest) in combination with the net8.0 branch. Looks nice again :-)

@samhouts How/When can we expect this fix in a upcoming update? Ive build my app with the latest version of MAUI 8.0.3 on VS2022 Preview. But i still have the borders on android.
