TableView cells disappearing on iOS

I'm having an issue with a TableView where cells become blank after scrolling through the table. This code works correctly on Xamarin.Forms 1.3.1.6296 Stable and stopped working correctly with Xamarin.Forms 1.3.2.6299-pre1. It doesn't work correctly on Xamarin.Forms 1.3.2.6316 Stable or the latest Xamarin.Forms 1.3.3.6322-pre3.

Here's the source code that you should be able to use to reproduce the issue. The cells contain a StackLayout because the layout is more complicated for those cells in the actual code. So, I can't just remove the StackLayout to fix the issue. I've also attached screenshots that show the issue. Let me know if there's something I can do to fix this.

    public class App : Application
    {
        public App ()
        {
            var page = new ContentPage ();
            page.Title = "Test Blank Rows";

            var tableView = new TableView ();
            tableView.HasUnevenRows = true;

            var tableHeaderSection = new TableSection ();

            var viewHeaderCell = new ViewCell ();

            var headerCellLayout = new StackLayout ();
            headerCellLayout.Orientation = StackOrientation.Vertical;
            headerCellLayout.Spacing = 6;
            headerCellLayout.HorizontalOptions = LayoutOptions.Fill;
            headerCellLayout.VerticalOptions = LayoutOptions.Fill;

            var largeNumberLabel = new Label ();
            largeNumberLabel.FontFamily = "HelveticaNeue-Light";
            largeNumberLabel.FontSize = 52;
            largeNumberLabel.Text = "90";
            largeNumberLabel.TextColor = Color.FromRgb(0.00392156885936856, 0.47843137383461, 0.996078431606293);
            largeNumberLabel.HorizontalOptions = LayoutOptions.Center;
            largeNumberLabel.VerticalOptions = LayoutOptions.Fill;
            headerCellLayout.Children.Add(largeNumberLabel);

            var nameLabel = new Label ();
            nameLabel.FontFamily = "HelveticaNeue-Light";
            nameLabel.FontSize = 17;
            nameLabel.Text = "Name: John Doe";
            nameLabel.HorizontalOptions = LayoutOptions.CenterAndExpand;
            nameLabel.VerticalOptions = LayoutOptions.Center;
            headerCellLayout.Children.Add(nameLabel);

            viewHeaderCell.Height = 100;
            viewHeaderCell.View = headerCellLayout;
            tableHeaderSection.Add (viewHeaderCell);
            tableView.Root.Add (tableHeaderSection);

            for (int sectionNumber = 1; sectionNumber < 11; sectionNumber++) {
                var tableSection = new TableSection ("Section #" + sectionNumber);

                for (int cellNumber = 1; cellNumber < 11; cellNumber++) {

                    var viewCell = new ViewCell ();
                    var viewCellLayout = new StackLayout ();
                    viewCellLayout.Orientation = StackOrientation.Horizontal;
                    viewCellLayout.Spacing = 6;
                    viewCellLayout.Padding = new Thickness (20, 10);
                    viewCellLayout.HorizontalOptions = LayoutOptions.Center;
                    viewCellLayout.VerticalOptions = LayoutOptions.Center;

                    var titleLabel = new Label ();
                    titleLabel.FontFamily = "HelveticaNeue-Light";
                    titleLabel.FontSize = 17;
                    titleLabel.Text = "Cell #" + cellNumber;
                    viewCellLayout.Children.Add(titleLabel);

                    viewCell.View = viewCellLayout;

                    tableSection.Add (viewCell);
                }

                tableView.Root.Add (tableSection);

            }

            page.Content = tableView;

            MainPage = page;
        }

        protected override void OnStart ()
        {
            // Handle when your app starts
        }

        protected override void OnSleep ()
        {
            // Handle when your app sleeps
        }

        protected override void OnResume ()
        {
            // Handle when your app resumes
        }
    }
