TPopup component does not work well in Android (RAd Studio 10.2. Tokyo)

I have just istalled “A FireMonkey Android Compatibility Patch for RAD Studio 10.2” and a lot of problems with Android disapppeared.

But I found out that component TPopup does not work well. The sample is very simple (see below).

Form contents only TButton and TPopup with TRectangle (Reactangle1.align := client) for visibility of popup. The popup should show after press button (Popup1.IsOpen:= true) but it does not show. Events “onPopup” and “onClosePopup” is called because opacity of button is changed (via code below) and I tested it in debug mode.

This project works well, if it is compiled in RAD Studio 10.1 Berlin.

type

  TForm1 = class(TForm)

     Button1: TButton;

     Popup1: TPopup;

     Rectangle1: TRectangle;

     procedure Popup1Popup(Sender: TObject);

     procedure Popup1ClosePopup(Sender: TObject);

     procedure Button1Click(Sender: TObject);

   private

     { Private declarations }

   public

     { Public declarations }

   end;

var

   Form1: TForm1;

 implementation

{$R *.fmx}

 procedure TForm1.Button1Click(Sender: TObject);

begin

  Popup1.IsOpen:= true;

end;

procedure TForm1.Popup1ClosePopup(Sender: TObject);

begin

  Button1.Opacity:= 1.0;

end;

procedure TForm1.Popup1Popup(Sender: TObject);

begin

  Button1.Opacity:= 0.5;

end;
