Steps to reproduce
- Open cs.m.wikipedia.org or de.m.wikipedia.org
- Try to login and provide incorrect password
MediaWiki:Wrongpassword should be shown and it should be localized if there is a translation in translatewiki available.
MediaWiki:Wrongpassword is not localized and for any language there is just English sentence, although the translations are available
