Locale dictionary not being included even though they exist

I have included several of the Plotly Locales in my project before (es, pt-br, zh-ch, ar) and now I am trying to include Norwegian (no) but the translations dictionary is not working when setting "no" as the locale. The dictionary is returning an empty object.
The formatting is working and the dates and times are being translated to norwegian as they should be, but the modebar buttons are remaining english even though the dictionary translations are included in the plotly.js/lib/locales/no.js file.

I tested this with a couple of other languages to check that I wasn't missing something and the same problem occurs if I try to use romanian (ro) - the formatting is correct and present, but the dictionary translations are not working even though they are included in the file.

Image shows the plotly config including several languages, see that the Spanish (es) locale shows the occupied dictionary translations as it should, but the Norwegian (no) locale shows an empty object for the dictionary, however, includes the formats.

Summary:
Norwegian locale dictionary is not working (returning empty objects when importing) even though the translations are included in plotly.js/lib/locales/no.js. Same problem occurs with Romanian - possibly others.

Start with lib/locales/no.js and compare its exported dictionary and formats with the working es locale. Reproduce the issue using the no and ro locales, then trace how locale dictionaries are imported or registered. Done means the no and ro dictionaries are populated and their modebar translations are applied, while formatting remains correct.
