SharePoint 2013: Access to strict mode caller function is censored

Question

I have created a clone button of "Save" button. When I modify any field and save it with the click of this clone button, it is saved. But while attaching/removing any file and saving this change using the click of this clone button, I got below error:

Access to strict mode caller function is censored

Any help in this !!

Below is the workaround provided in link.

function hackEventWithinDoPostBack() {
    var originalEventDescriptor = Object.getOwnPropertyDescriptor(Window.prototype, "event");
    var hackEventVariable = false;
    var eventPropertyHolder;
    Object.defineProperty(window, "event", {
        configurable: true,
        get: function get() {
            var result = originalEventDescriptor ? originalEventDescriptor.get.apply(this, arguments) : eventPropertyHolder;
            if (result || !hackEventVariable)
                return result;
            return {};
        },
        set: function set(value) {
            if (originalEventDescriptor)
                originalEventDescriptor.set.apply(this, arguments);
            else
                eventPropertyHolder = value;
        }
    });

    var originalDoPostBack = window.__doPostBack;

    window.__doPostBack = function hackedDoPostBack() {
        hackEventVariable = true;
        originalDoPostBack.apply(this, arguments);
        hackEventVariable = false;
    };
}

• Make sure you are using latest Firefox version. It seems a Firefox problem.
• Try with a different browser.
• Make sure your cloned button have the same JavaScript inline like original button.
