In Chrome for Mac, one can \"overscroll\" a page (for lack of a better word), as shown in the screenshot below, to see \"what\'s behind\", similar to the iPad or iPhone.
You can use this code to remove touchmove predefined action:
touchmove
document.body.addEventListener('touchmove', function(event) { console.log(event.source); //if (event.source == document.body) event.preventDefault(); }, false);
