Swiped Event of SwipeGestureRecognizer does not contain actual direction

Description

The Swiped event of SwipeGestureRecognizer does not contain actual direction

Steps to Reproduce

Create a new page and in Xaml:

<!-- Swipe Gesture -->
<Label Text="Swipe Gesture" class="featureHeader" Margin="0,20,0,10"/>
<BoxView BackgroundColor="Black" Margin="0,0,0,10" HeightRequest="1"/>
<Label Text="Swipe right-to-left or left-to-right on the green box below." Margin="0,10"/>
<BoxView BackgroundColor="Lime" WidthRequest="300" HeightRequest="300">
    <BoxView.GestureRecognizers>
        <SwipeGestureRecognizer
            Direction="Right, Left"
            Swiped="SwipeGestureRecognizer_Swiped" />
    </BoxView.GestureRecognizers>
</BoxView>

In code:

private async void SwipeGestureRecognizer_Swiped(object sender, SwipedEventArgs e)
{
    await DisplayAlert("Swiper No Swiping!", $"Yay! You swiped to the {e.Direction}!", "Close");
}

Run the app and swipe either way,
