I want to write a function to listen to sessionStorage. I found that the following code works fine on both computers and Android phones, but it suddenly stopped working on iOS phones recently. Does anyone know how to fix it?

Watch_Storage: function () {
            var originalSetItem = sessionStorage.setItem;
            sessionStorage.setItem = function (key, value) {
                let event = new Event("setItemEvent");
                event.key = key;
                event.newVal = value;
                window.dispatchEvent(event);
                originalSetItem.apply(this, arguments);
            }
        },
setItemEventHandler: function (e) {
            console.log(e.newVal);
        },

this.Watch_Storage();
window.addEventListener("setItemEvent", function (e) {
 this.setItemEventHandler(e);
});

I tried rewriting it as document.addEventListener, but it still doesn’t work. Currently, the only solution I can think of is to temporarily use setInterval to periodically fetch new data when detecting iOS. I can’t think of any other solutions.
