Greetings
It's about the 'Github News Feed Filter' script.
I've just noticed that the Actions list is no longer populated, I'm getting this error twice instead:
Uncaught TypeError: Array.forEach is not a function line 476
at HTMLAnchorElement.filterTabInnerClick
This must have happened due to the recent GitHub HTML changes.
By the way, I've noticed that, clicking to switch to either the Repositories or Users tabs
causes the sidebar to become too thin in width.
(this is an irrelevant issue that's been happening a long time now)
Here is a screen capture (TM in Chrome) to see what I mean:

Tested v8.2.8 with fresh profile of both Chrome 89/Firefox 87
using latest Tampermonkey beta 4.12.6132/Violentmonkey beta 2.12.11.2 .
I tried, but can't seem to be able to fix it myself.
Thank you
