As of a week or so ago all the demos in the angular documentation have stopped working. It just displays a loading spinner icon but the demo never loads. This is on all of the pages in the angular docs. If I choose the option to view in stackblitz then it works fine. I show an error in my JS console that might be causing the issue.

Those demos are very helpful so it would be great to get them working again.
