When a banner is cloned and translate is enabled in CentralNotice the messages are not copied into the CNBanner namespace. The end result is that it appears to translate like the banner has not been translated. We should probably copy all translations into CNBanner and set the group state to approved on a clone.
Very strangely, it did just copy the CNBanner translations for exactly one language (out of >50 existing translations), namely Kazakh (kk): https://meta.wikimedia.org/w/index.php?title=Special:Contributions&offset=20141019070000&limit=11&tagfilter=&contribs=user&target=Tbayer+%28WMF%29&namespace=866 (All the edits there dated 04:50, 18 October 2014 are automated edits resulting from cloning a translated banner.) That's only a very partial solution for this bug though ;) In seriousness, it would be great to have this bug solved. I currently do this via bot (see e.g. https://meta.wikimedia.org/w/index.php?title=Special:Contributions/HaeBot&offset=20141019080000&target=HaeBot ); having MediaWiki do this automatically would be much preferable.
