Buttons still clickable outside layout/screen?

So I noticed that you can still click on buttons that are outside the layout when the game is played from a browser such as Safari on iPhone. It seems strange that this is possible.

Is there a way to prevent this? I've got buttons that I position on and off screen when needed. I need to keep them somewhere right?

Now I think of it I could create and destroy them, but is there a way to prevent buttons from being clicked outside the layout?

Thanks.

It is normal because whenever you see the button, you can reach it.

Obviously that you could move it to X : 5000, Y : 5000 (far far away)

Or you can put a condition that you want to push that button in that case only.

Thanks.

I just thought at first that the layout would restrict anything outside of it once running the game.

I'll try your suggestions.
