Ihor, Nathaniel — Makes sense. The fix belongs in emacs-jupyter, not upstream.
Nathaniel — I submitted a PR on the emacs-jupyter side that addresses this: https://github.com/emacs-jupyter/jupyter/pull/611 It may overlap with or complement the diagnosis you traced in org-babel-where-is-src-block-result. Happy to coordinate there. Thanks all for the thorough response on this. Pete
