They did.

It didn't. IIRC a temp buffer was created 2 or 3 times every time
I would move point. The problem is that this *somehow* triggered a
feedback loop with treemacs and magit feeding off each other. I
haven't really understood what happened there as that would require
some very deep digging inside magit's internals. There's a recipe for
emacs -q in the github issue if you want to see this for yourself.

Way ahead of you ;)
