In Serbia there are two language codes and those are `sr_RS` (Cyrillic) and `sr@latin` (Latin). Inside of the `web/static/lib/moment/locale` folder, the two langs are registered as `sr-cyrl.js` and `sr.js` respectively. The `load_locale` controller wasn't loading the right langs for neither case. X-original-commit: 65d5ab801f22b42a0f94fe4b86f68ace451ea184 Part-of: odoo/odoo#114565
