FWIW, reverting the change made to org-babel-exp-results in the following
patch seems to fix my issue.


commit 8e54cafeb286ea5eb25565a637b121a2f597c48b
Author: Nicolas Goaziou <mail@nicolasgoaziou.fr>

    Fix noweb expansion during export

    * lisp/ob-core.el (org-babel-sha1-hash): Add optional argument to
      specify context.
    (org-babel-execute-src-block): Use new argument.
    * lisp/ob-exp.el (org-babel-exp-src-block): Use new argument.
    (org-babel-exp-results): Fix context.
