Should be fixed now on master.

I wonder whether we should actually cherry-pick this to the release
branch.  The original recipe doesn't trigger the problem there, but
that's because json-pretty-print-buffer does modify the buffer on
emacs-27.  If it didn't, we'd probably have the same problem in Emacs
27.

Thoughts?
