An ugly workaround could be using :python header argument to explicitly
set the python path.
Org babel uses a temporary buffer + `process-file' to evaluate code
blocks with no session. The current directory is being set by
let-binding `default-directory'. You can look into
`org-babel-execute-src-block' (sets `default-directory') ->
"(funcall cmd body params)" -> `org-babel-execute:python' ->
`org-babel-python-evaluate' ->
`org-babel-python-evaluate-external-process' -> `org-babel-eval' ->
`org-babel--shell-command-on-region' -> `process-file' call chain and
check where the envrc settings get lost.
I am unsure how and why the Org's approach is not working together with
envrc.el. It might be helpful to add envrc devs into the loop or debug
things yourself.

This looks like "with-editor" package doing something funny. Not Org.
