[Feedback, UWP] Swipe Gesture Recognizer breaks scrolling on ScrollView

Description

When SwipeGestureRecognizers are added to a stacklayout in a scrollview the scrollview will no longer scroll with touch.

The only way to see this behavior is to use the simulator or a device where you can actually touch the screen.

<ScrollView BackgroundColor="Yellow">
	<StackLayout Orientation="Vertical" BackgroundColor="Purple">
		<StackLayout.GestureRecognizers>
			<SwipeGestureRecognizer Direction="Left" Swiped="OnTestLayoutLeftSwiped" />
			<SwipeGestureRecognizer Direction="Right" Swiped="OnTestLayoutRightSwiped" />
		</StackLayout.GestureRecognizers>

		<Label Text="Swipe me" x:Name="lblSwiped" WidthRequest="200" HeightRequest="300" BackgroundColor="Green"></Label>
		<Label Text="Swipe 1" WidthRequest="200" HeightRequest="300" BackgroundColor="Blue"></Label>
		<Label Text="Swipe 2" WidthRequest="200" HeightRequest="300" BackgroundColor="Aqua"></Label>
		<Label Text="Swipe 3" WidthRequest="200" HeightRequest="300" BackgroundColor="Yellow"></Label>
	</StackLayout>
</ScrollView>

private void OnTestLayoutLeftSwiped(object sender, SwipedEventArgs e)
{
    lblSwiped.Text = "Swiped Left";
}

private void OnTestLayoutRightSwiped(object sender, SwipedEventArgs e)
{
    lblSwiped.Text = "Swiped Right";
}
