OnFormResize not detected

With tms Web Core VS (Win10 os with chrome browser) when resize form only vertically OnresizeForm event is not detected.
It needs mandatory to resize horizontaly the form to detect it.
Thanks

I retested this here and I cannot reproduce this.
I simply added the OnResize event handler for the form as:

procedure TForm1.WebFormResize(Sender: TObject);
begin
  console.log('resize');
end;

and this event is also triggered when I vertically resize the browser window.

Hi Bruno,
create a sub WebForm inside a mainform web form.
Put your onResize event on subweb form and see that is not triggered when you resize only verticaly.

Thanks

Tested it with demo Demo\Basics\MultiForm using an OnResize event handler for TForm2 and it works as expected.
