Xamarin.Forms：ScrollView 在 Windows 10 移动版上不滚动

Question

此代码在 iOS 和 Android 上运行良好，但在 Windows 10 移动设备（Microsoft Lumia 650，版本：1511，内部版本：10.0.10586.11）上运行良好：

public App()
{
    var layout = new StackLayout
    {
        Orientation = StackOrientation.Vertical,
        Padding = 0,
        Children =
            {
                new Button { Text = "A" },
                new Button { Text = "B" },
                new Button { Text = "C" },
                new Button { Text = "D" },
                new Button { Text = "E" },
                new Button { Text = "F" },
                new Button { Text = "G" },
                new Button { Text = "H" },
                new Button { Text = "I" },
                new Button { Text = "J" },
                new Button { Text = "K" },
                new Button { Text = "L" },
                new Button { Text = "M" },
                new Button { Text = "N" },
                new Button { Text = "O" },
                new Button { Text = "P" },
                new Button { Text = "Q" },
                new Button { Text = "R" },
                new Button { Text = "S" },
                new Button { Text = "T" },
                new Button { Text = "U" },
                new Button { Text = "V" },
                new Button { Text = "W" },
                new Button { Text = "X" },
                new Button { Text = "Y" },
                new Button { Text = "Z" },
            },
    };
    var scrollView = new ScrollView { Content = layout };

    // The root page of your application
    MainPage = new ContentPage
    {
        Content = scrollView,
    };
}

滚动视图根本不滚动。我可以看到滚动条，但它不滚动。我尝试与HorizontalOptions/VerticalOptions 一起玩，但这也无济于事。在模拟器中，它通过鼠标滚动来工作。 Label 也会出现同样的问题。

这里有什么问题？
