Promise.all and Promise.allSettled doesn't work if the promise array has been created in a different frame.

Method isInstanceOf (used in each method) doesn't work correctly for arrays created in a different frame. See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/isArray

Array.isArray is the better alternative but is not implemented in all browser so I would suggest following:

        function isArray(obj) {
            if (Array.isArray && Array.isArray(obj)) {
                return true;
            }

            if (isInstanceOf(obj, Arr)) {
                return true;
            }

            if (Object.prototype.toString.call(obj) === "[object Array]") {
                return true;
            }

            return false;
        }
}

Could you help to make a PR for it?

Of course. I will make a PR this evening.
