Reproduce:

• Open an East-Asian language wiki (such as zh.wikipedia), the MediaWiki:Wikibase-dataitem shows "{{WBREPONAME}}项目" and the magic word "{{WBREPONAME}}" reports "维基数据" (localized name of Wikidata).
• In "Tools" sidebox, the "Wikidata item" link displays as "Wikidata项目" ("Wikidata" was not localized).
