Please make sure that the language(s) used are static for anything in the content of a page. In particular, it should not depend on the user interface language, as that would impose a heavy performance penalty on the user.

There is a problem that we had not noticed before: T140792.

mw.wikibase.label() takes into account the user's default language, and does not change language when ?uselang=xx is added to the URL. This is
I see two possible solutions:

  1. change the behavior of mw.wikibase.label() so that it takes into account ?uselang
  2. provide a Lua function that retrieves the user's language using the same criteria as mw.wikibase.label() so that we can adapt Lua modules to fix the ?uselang= issue locally.

I've created T142906: Data access in user language doesn't obey the uselang get parameter for that.
