**Steps to reproduce:**
* Look at the list of languages e.g on https://test.wikidata.org/wiki/Special:NewItem
**What happens?**
`mul` can be found at the very end of the list.
**What should have happened instead?**
`mul` should be found at the position defined by sorting by language code.
**Notes:**
* In T329626 we wanted the list of languages sorted alphabetically (including "multiple languages"). We decided to split this task out from the original task.
* Lucas started a patch https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Wikibase/+/901555
**Notes about the status quo:**
The list is currently a union of MediaWikiContentLanguages and additional StaticContentLanguages
The list of term language codes is:
* all codes supported by MediaWiki core
**MediaWiki ensures this list is sorted
**only in production, this also includes agq, bag etc., via wmgExtraLanguageNames
*a hard-coded extra set of language codes: agq, bag, etc.
**this list is sorted in the source code
*mul, if enabled
So on production Wikidata, the second and third list item make no difference; on a default Wikibase, the third list item has no effect, but agq/bag/etc. will be after the regular language codes; on Test Wikidata, the second list item makes no difference (redundant), but the third list item adds an unsorted language code at the end.
**Open questions:**
*What Sorting do we want?
** Sarai wanted to sort the list alphabetically by the language name, originally.
** The dev team asks is sorting by language code would be good enough? It would have the advantage that it is only one order for all UI languages.
** Manuel sees some upsides for keeping the status quo: MUL is also sorted last in the termbox, so maybe this position is intuitive in the list as well.
**Acceptance criteria:**
[] The languages are sorted alphabetically / by language code / as is (TBD).
