In this edit, the zh-yue interwiki was moved above the categories. However, as an interwiki, it should have remained at the bottom. This may be because https://en.wikipedia.org/w/api.php?action=sitematrix&format=xml includes https://zh-yue.wikipedia.org under the language code yue rather than zh-yue. However, MediaWiki itself does recognize [[zh-yue:$]] as well, displaying it in the Vector-2010 sidebar rather than inline.
