**Motivation**
Termbox is showing languages considered "preferred by the user" (T213720) in the "more languages" sections. These languages are sourced from their babel box and can, apparently, contain language codes that //do// exist but are not considered to be full fledged MediaWikiContentLanguages (wb terminology) but [[ https://github.com/wikimedia/jquery.uls/blame/master/src/jquery.uls.data.js#L1051 | delegate ]] to another language code instead. However, it is not possible to add anything to these languages or save them on the wiki, since the language is not an official project language, and the display is broken. Currently, the desktop termbox fails when saving.
**Example for bug appearing (in new termbox layout)**
**Example for babel box languages**
The language code for which this happened was **fil**, resulting in a weird looking and behaving first line
{F28469501}
**Acceptance Criteria**
[] The termbox doeas not display "delegating" language codes in the termbox
