Just add this polyfill:

        NodeList.prototype.forEach = function (callback/*, thisArg*/) {

            var T, k;

            if (this == null) {
                throw new TypeError('this is null or not defined');
            }

            // 1. Let O be the result of calling toObject() passing the
            // |this| value as the argument.
            var O = Object(this);

            // 2. Let lenValue be the result of calling the Get() internal
            // method of O with the argument "length".
            // 3. Let len be toUint32(lenValue).
            var len = O.length >>> 0;

            // 4. If isCallable(callback) is false, throw a TypeError exception. 
            // See: http://es5.github.com/#x9.11
            if (typeof callback !== 'function') {
                throw new TypeError(callback + ' is not a function');
            }

            // 5. If thisArg was supplied, let T be thisArg; else let
            // T be undefined.
            if (arguments.length > 1) {
                T = arguments[1];
            }

            // 6. Let k be 0.
            k = 0;

            // 7. Repeat while k < len.
            while (k < len) {

                var kValue;

                // a. Let Pk be ToString(k).
                //    This is implicit for LHS operands of the in operator.
                // b. Let kPresent be the result of calling the HasProperty
                //    internal method of O with argument Pk.
                //    This step can be combined with c.
                // c. If kPresent is true, then
                if (k in O) {

                    // i. Let kValue be the result of calling the Get internal
                    // method of O with argument Pk.
                    kValue = O[k];

                    // ii. Call the Call internal method of callback with T as
                    // the this value and argument list containing kValue, k, and O.
                    callback.call(T, kValue, k, O);
                }
                // d. Increase k by 1.
                k++;
            }
            // 8. return undefined.
        };
