JavaScript error on click of Load More button in Embedded Timelines widget on IE browser


I am working on adding Embedded Timelines widget on our website. After adding it to the page, when I click on Load More button, the widget.js script is throwing following JavaScript error.
Line: 38
Error: Unable to get property ‘getAttribute’ of undefined or null reference

I can only repro this on IE browser. In chrome and firefox this works fine. Any help would be really appreciated.



Thanks for the report. In fact I did reproduce it in Chrome where it says:
Uncaught TypeError: Cannot call method ‘getAttribute’ of undefined


Do you know if anyone can help us with this? We need to resolve this asap to incorporate a module on Microsoft property.
