Hi, after I updated my Emacs this morning to d656be9794d (emacs-30 branch) I am now not seeing this problem. I see in 5eaf0c784bf that there was a small, seemingly unrelated change to to info-look.el, but that is the only thing that jumps out at me. So, I'm not sure how the problem was resolved, but hopefully it is gone for good.
I also vaguely recall doing a home reconfigure a day or two ago, so perhaps that played into it somehow. -- Christopher Howard
