I need my web application to behave as a native mobile app. For this I needed to prevent pinch-to-zoom and double tap zooming on all browsers. In Chrome and Firefox it was easy:

On Safari its a challenge. Here I found how to prevent pinch-to-zoom and to disable double-tap-zoom. But when you are scrolling and pinching to zoom, its zooming. My question is if there is way to block it also on scrolling?
