The wait mark animation does not disappear on Xamarin.Forms

Question

I am developing with Xamarin.

When I scroll a CollectionView, the wait mark animation does not disappear even after the scrolling is finished. How can I remove it?

        <StackLayout Spacing="20" Padding="15" >
            <RefreshView x:DataType="local:ItemDetailViewModel"
                 IsRefreshing="{Binding IsBusy, Mode=TwoWay}">
                <CollectionView x:Name="ItemsListView"
                 ItemsSource="{Binding EventItems}" SelectionMode="None">

                 <!--  ...template...  -->

                </CollectionView>
            </RefreshView>

        </StackLayout>

When you finish the task inside the refresh command you need set to IsBusy to False.

<RefreshView IsRefreshing="{Binding IsBusy}"
             Command="{Binding RefreshCommand}">

</RefreshView>

public ICommand RefreshCommand { get; }

public ItemsViewModel()
{
    Title = "Browse";
    Items = new ObservableCollection();
    RefreshCommand = new Command(ExecuteRefreshCommand);
}

bool _isBusy;

public bool IsBusy
{
    get => _isBusy;
    set
    {
        _isBusy = value;
        OnPropertyChanged(nameof(IsBusy));
    }
}

void ExecuteRefreshCommand()
{
    // DO your task and then
    // Stop refreshing
    IsBusy = false;
}
