As [reported here](https://www.mediawiki.org/wiki/Topic:Sep6jn56upwzwqv9), a user landing CX in French Wikipedia gets French-to-Bulgarian as the default language pair when creating a new translation. Later, Bulgarian appears as a red interlanguage link (which is confusing because Bulgarian is not a language the user speaks).
The following issues should be solved:
- Whichever are the default languages proposed to the user, those should not be stored in the list of common languages unless the user explicitly selects them (or confirms the default ones by starting a translation).
- The local language makes more sense to be proposed as the target language, not the source.
- As the source language, if there is no better information (such as previous selections), English may be a better default than a random (or alphabetical) choice as the default.
