function prevent(e) { e.preventDefault() }
// you could target also another nested DOM element
document.body.addEventListener('gesturechange', prevent)
document.body.addEventListener('gesturestart', prevent)
document.body.addEventListener('gestureend', prevent)

Add this to onClick event

event.preventDefault();
