[Bug] [.NET 9] SfShimmer [v1.3] in CollectionView Fails to Display During Pull-to-Refresh

[malsabi]

Description

When using the Syncfusion SfShimmer control in a .NET MAUI application to indicate the loading state within a CollectionView, the shimmer effect fails to display during a pull-to-refresh operation on Android. Instead of showing the shimmer wave or placeholder effect, the CollectionView remains blank until the items are loaded. However, the SfShimmer control works as expected on iOS and Windows platforms, where the shimmer effect displays correctly during the loading process. This issue appears to be platform-specific and affects the user experience on Android.

Steps to Reproduce

1. Clone the repository from the provided link: [https://github.com/malsabi/ShimmerIssue].
2. Open the project in Visual Studio.
3. Build and run the application on an Android emulator or physical device.
4. Trigger the pull-to-refresh action on the CollectionView.
