Added non-passive event listener to a scroll-blocking 'touchstart' event

Question

Suddenly today out of nowhere I started getting this one on every page on our website

Added non-passive event listener to a scroll-blocking \'touchstart\' event.         


        

Answer 1

I am using various events and this seems to solve my use case

(function () {
    if (typeof EventTarget !== "undefined") {
        let func = EventTarget.prototype.addEventListener;
        EventTarget.prototype.addEventListener = function (type, fn, capture) {
            this.func = func;
            if(typeof capture !== "boolean"){
                capture = capture || {};
                capture.passive = false;
            }
            this.func(type, fn, capture);
        };
    };
}());
