Note that this problem is still persisting for me, both in Emacs 26 and also in
Emacs 27.1
which I just upgraded to.
I have implemented a workaround to the uniquify-managed list growing
Exponentially after using revert-buffer. See this patch

No, uniquify-after-kill-buffer-p is set to t in my session; no

The attachment seems to be missing. But anyway, I have a simple
reproducer now, so we don't need any more backtraces. I found setting
uniquify-after-kill-buffer-p to nil was needed to reproduce this, do you
have that setting in your init?
