=== Description
Currently we do not have any special handling of the language button or menu for the situation where an article has no other available languages. While we don't want to over-invest in a short-term solution here it would be great to at least have a minimal solution here.

[] Link to Content Translation special page with the current article selected (see T275147#6863710 for details). Link similar to:
