Prevent iOS 11.3 overflow bouncing

I've been making use of the preventDefault technique on the touchmove event since now, when I noticed it doesn't seem to work anymore on iOS 11.3, for neither Safari, nor Chrome or Firefox:

document.ontouchmove = function(event){
    event.preventDefault();
} 

Has anything changed now in iOS? What's the way of preventing the bouncing at the top or end of the page?

It was caused by a bug of WebKit. Bug 182521

Try window.addEventListener("touchstart", preventBouncing, {passive: false} ); as a workaround.
