IE issue on 1.2.4

[kamituel]

It seems IE 10, 11 and Edge all have issue with the way StorageEvent is being used - as a constructor.

This breaks session storage in those browsers. The only way to get it to work is to polyfill StorageEvent to act as a function (constructor), with something like:

(function () {
  try {
    new window.StorageEvent("storage");
  } catch (e) {
    console.log('Using a polyfill for StorageEvent.');

    function StorageEvent (event, params) {
      var evt = document.createEvent('StorageEvent');
      return evt;
     }

    StorageEvent.prototype = window.StorageEvent.prototype;
    window.StorageEvent = StorageEvent;
  }
})();
