Error creating form with firemonkey border

Using Delphi's RAD Seattle update 1 when creating a form at runtime, if the main form is with the BorderStyle property other than none I get an error. This problem happens using firemonkey and compiling for Android.

To reproduce the error is simple, just create a firemonkey application, include two forms, do not allow automatic creation, in main form set BorderStyle other than none and call creation of the second form .

Error Displayed :

android.view.ViewRootImpl$CalledFromWrongThreadException:Only the
original thread that created a view hierarchy can touch its views.

Follow the code:

procedure TfrmAgendamento.lstProdutosItemClick(const Sender: TObject;
  const AItem: TListViewItem);
begin
  if not assigned(frmExpedicao) then
    frmExpedicao := tfrmExpedicao.Create(nil);
  frmExpedicao.Show;
end;
