@AzhanL thanks for pointing this out! My preference is to avoid copying the javascript. I tried to fix this with a different solution but this is far from my expertise. Let me know what you think #764

[AzhanL]

@the-other-tim-brown I reviewed #764, that solution would unfortunately not work due to the CSP in place (left details on that PR). We would need to either add the CSS/JS into the repo or update the CSP policy to allow a CDN. Don't know if updating the policy is doable.

Importing the JS allows loading multiple fonts later without importing them into the repository.

Updating the CSP policy would be the ideal solution, though. I'll check around to see where I can ask for that change.
