CT 4.2 Chart Freeze Adding a Canvas

Hi, 

I have noticed a break in functionality from CT 4.1, when you add a canvas to a chart for an indicator it freezes the chart and you cannot move it, I have added some code as an example.

namespace cAlgo
{
    [Indicator(AccessRights = AccessRights.None)]
    public class CanvasTest : Indicator
    {
        [Parameter(DefaultValue = "Hello world!")]
        public string Message { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        protected override void Initialize()
        {
             var blueRectangle = new Rectangle()
            {
                Width = 80,
                Height = 60,
                FillColor = Color.Blue,
                Left = 10,
                Top = 10
            };

            Canvas canvas = new();
            
            canvas.AddChild(blueRectangle);
            
            Chart.AddControl(canvas);
        }

        public override void Calculate(int index)
        {
            // Calculate value at specified index
            // Result[index] = 
        }
    }
}
