One weird tangentially related thing is checking whether a PR is merge:able after solving a conflict in this repo[1] for some reason takes several minutes. Maybe because there are 1000 commits in the same file. Doesn't seem UI related but weird regardless.

The emojis I had at the beginning of the list name don't render anymore (they show up as :eyesore_emoji_name: instead) and the list is sorted alphabetically now instead of by last modified. Also it's one looong list instead of a small scroll-able container like it used to be.
This is on Firefox btw. Now I'm seriously thinking about moving these GitHub "bookmarks" into a separate place like a bookmark manager even if I lose a bit of convenience.
