Background Color not working in ViewCellRenderer After 1.3.3 Upgrade

This code used to work and the background color would be applied.

But after 1.3.3 upgrade the background color is not applied.

public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv)
    {
        var cell = base.GetCell(item, reusableCell, tv);

        cell.Accessory = UIKit.UITableViewCellAccessory.DisclosureIndicator;

        cell.BackgroundColor = Color.FromHex("7eeeeeee").ToUIColor();

        return cell;
    }

Please help us determine why this is currently not working.
