CollectionView with IsGrouped="True" - RemainingItemsThresholdReachedCommand not Firing

[snufffgit]

Description

I Have a Grouped CollectionView, RemainingItemsThresholdReachedCommand is not firing correctly.

            <CollectionView
                IsGrouped="True"
                ItemsSource="{Binding Activity}"
                RemainingItemsThreshold="{Binding RemainingItemsThreshold}"
                RemainingItemsThresholdReachedCommand="{Binding GetDataCommand}">
                <CollectionView.GroupHeaderTemplate>
                    <DataTemplate x:DataType="{x:Null}">
                        <ContentView>
                            <Label
                                VerticalTextAlignment="Center"
                                FontFamily="MediumFont"
                                Text="{Binding Key,
                                    Converter={converters:DateConverter}}"/>
                        </ContentView>
                    </DataTemplate>
                </CollectionView.GroupHeaderTemplate>
                <CollectionView.ItemTemplate>
                    <DataTemplate x:DataType="models:ActivityData">
                        ...
                    </DataTemplate>
                </CollectionView.ItemTemplate>
            </CollectionView>

Consider that IsGrouped in CollectionView was not working until a recent version.
