I'm afraid I'm having trouble testing this one. I don't see any of the implemented changes after running invenio-cli assets build or invenio-cli assets watch. No improvement from clearing my virtual environment (pipenv --rm) or building and running the web app from scratch in a container (invenio-cli container --build).

I get the following after invenio-cli assets build which may be related:
