@sh.itjust.worksThis could be what you're looking for. Their main implementation is a gitea fork, but I've seen mentions of gitlab as well. Unfortunately I don't think github would ever consider being compatible, that would just lose them users.
I was originally using Jerboa, but scrolling was really laggy for some reason so I ended up switching to Liftoff and it's been much better.
I think I fixed the getting stuck open problem (at least for me). I added this at the end of the mouseenter setup function around line 152.
if (!userCard.querySelector(":hover") && !userLink.querySelector(":hover")) {
userCard.style.display = "none";
}
"If mouse is gone by the time we're ready, then hide."
