Prevent nested TeeChart from receiving mouse events at design time

Question

I made a following simple component with a nested TeeChart. There nothing more in it.

unit ExperimentalChart;

interface

uses System.Classes, Vcl.Controls, VclTee.TeeGDIPlus, VCLTee.TeEngine,
  VCLTee.TeeProcs, VCLTee.Chart;

type
  TExperimentalChart = class(TCustomControl)
  private
    FChart: TChart;
  protected
    procedure CreateHandle(); override;
  public
    constructor Create(AOwner: TComponent); override;
    destructor Destroy(); override;
  published
  end;

procedure Register();

implementation

uses System.SysUtils;

procedure Register();
begin
  System.Classes.RegisterComponents('Experimental', [TExperimentalChart]);
end;

constructor TExperimentalChart.Create(AOwner: TComponent);
begin
  inherited;
  FChart := TChart.Create(nil);
  FChart.ClearChart();
  FChart.View3D := False;
end;

procedure TExperimentalChart.CreateHandle();
begin
  inherited;
  FChart.Parent := Self;
  FChart.Align := alClient;
end;

destructor TExperimentalChart.Destroy();
begin
  FreeAndNil(FChart);
  inherited;
end;

end.

When I am using this component at design time and want to move the component on the form, TChart receives all the mouse events and an error box appears:

Cannot focus a disabled or invisible window.

How to inhibit passing events to the chart and allow moving the component at design time?
