Bug in horizontal ScrollToAsync in Android

$

The new ScrollToAsync function seems to work well on iOS and Android until I came across a bug on Android.

When I call ScrollToAsync the animation always jumps back to position 0 in ScrollView, after this it animates to the correct position (somehow the animation starting position always resets to 0)

MyScroll = new ScrollView { Orientation = ScrollOrientation.Horizontal, BackgroundColor = Color.Red };

StackLayout testContent = new StackLayout { Orientation = StackOrientation.Horizontal };
for (int i = 0; i < 30; i++) {
        testContent.Children.Add (new Label { Text = "Item" + i, WidthRequest = 100 });
}

MyScroll.Content = testContent;

rl.Children.Add (
        MyScroll,
        Constraint.Constant(0),
        Constraint.Constant(0),
        Constraint.RelativeToParent((Parent) => { return Parent.Width; }),
        Constraint.Constant(50)
);

And I use the following method to test:

private async void MyTestMethod()
{
    await Task.Delay(3000);
    await MyScroll.ScrollToAsync (200, 0, true);        // Works as expected

    await Task.Delay(3000);
    await MyScroll.ScrollToAsync (600, 0, true);        // Animation jumps back to start of scrollview, and then quickly scrolls to pos 600

    await Task.Delay(3000);
    await MyScroll.ScrollToAsync (1000, 0, true);       // Animation jumps back to start of scrollview, and then quickly scrolls to pos 1000
}

The code above works as expected on iOS and when I implement the scrollview vertically everything works as expected. Bug is only occuring horizontally on Android.
