Scrollbar is hidden on mobile when using e.preventDefault() in touchMove event When the page scroll gets fired from JS by using a touchmove event and using e.preventDefault() inside it, then the page scrolls as normally but the scroll bar is not visible during the process. This way the user doesn't have a way to know in which part of the page is or get a real felling of scrolling the page. Steps to reproduce: - Open the file I attach in Safari or Chrome for iOS - Tap and swipe down a bit - You'll see how the page scrolls down fired by JS but the scrollbar is not visible. This didn't happen in past versions of Safari or Chrome for iOS.
