Different cookie handlers for two instances of chrome in one form

I am using DCEF3 on Delphi XE3.

Task . Create different cookie stores for different TChromium instances.
Problem . I create different ICefCookieManager instances for each TChromium instance and return to the GetCookieManager event.

Sample code:

type
  TForm1 = class(TForm)
    Button1: TButton;
    Button2: TButton;
    Chromium1: TChromium;
    Chromium2: TChromium;
    procedure Button1Click(Sender: TObject);
    procedure Button2Click(Sender: TObject);
    procedure FormCreate(Sender: TObject);
    procedure Chromium1GetCookieManager(Sender: TObject;
      const browser: ICefBrowser; const mainUrl: ustring;
      out Result: ICefCookieManager);
    procedure Chromium2GetCookieManager(Sender: TObject;
      const browser: ICefBrowser; const mainUrl: ustring;
      out Result: ICefCookieManager);
  private
    { Private declarations }
      CookieManager: ICefCookieManager;
      CookieManager2: ICefCookieManager;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

procedure TForm1.FormCreate(Sender: TObject);
begin
    CookieManager:=TCefCookieManagerRef.New('C:\Cookies\1');
    CookieManager2:=TCefCookieManagerRef.New('C:\Cookies\2');
end;

procedure TForm1.Chromium1GetCookieManager(Sender: TObject;
  const browser: ICefBrowser; const mainUrl: ustring;
  out Result: ICefCookieManager);
begin
    Result:=CookieManager;
end;

procedure TForm1.Chromium2GetCookieManager(Sender: TObject;
  const browser: ICefBrowser; const mainUrl: ustring;
  out Result: ICefCookieManager);
begin
    Result:=CookieManager2;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
    Chromium1.Load('http://somesite.com');
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
    Chromium2.Load('http://somesite.com');
end;

      

        
        
        
      

    

If I add an event ShowMessage('First')

to Chromium1GetCookieManager

and ShowMessage('Second')

to Chromium2GetCookieManager

, the message "First" is always displayed, regardless of whether I press button1 or button2.
In other words, Chromium1GetCookieManager is called for both instances.
