FWIW, reverting the change made to org-babel-exp-results in the following
patch seems to fix my issue.
commit 8e54cafeb286ea5eb25565a637b121a2f597c48b
Author: Nicolas Goaziou <address@hidden>
Date: Sat Jun 23 23:04:45 2018 +0200
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.
