IE11 - CustomEvent Polyfill stop triggering events after PDF download #10

Hi,

As CustomeEvent is not supported in IE11, so added polyfill from MDN and also tested this polyfill.

That is working fine in other browser(Chrome, Firefox) and even IE11 but it stops triggering/listening event after very specific steps. That is download a PDF and trigger "change" event.

Please check demo in IE11/Win7.

Steps to reproduce the bug:

1 - Download PDF

2 - Change Checkbox, it will call native "change" event but CustomEvent does not trigger.

NOTE: Open DevTool's console to visualize console.logs.

Again Demo URL - https://goo.gl/bYYRHf

Also reported this issue at Microsoft's community.

Kindly suggest alternative polyfill/solution/suggestion. Thanks
