On NativeToolkit.ShowAlert ()or NativeToolkit.ShowConfirm(), the user can tap on the empty space outside of the popup, closing the popup.
On iOS, this doesn't occur as the user cannot close the popup by tapping outside of the popup window.
But the Action<bool> callback provided is not called when this happens.
Is there a way Unity can handle this event that the popup has been closed without the user selecting an option?
