The English Wiktionary uses [[ https://en.wiktionary.org/wiki/MediaWiki:Gadget-legacy.js | javascript ]] to create collapsible elements, and although the javascript has not been changed recently, it has broken in such a way that elements are collapsed with no way of expanding them, which leads us to suspect that something may have changed in the site software to cause the breakage. For example, in the entry [[ https://en.wiktionary.org/wiki/dove | dove ]], some quotations directly underneath the definitions, the box of derived terms, and the box of translations are all no longer expandable, so that content cannot be seen except in edit mode. This problem is discussed at Wiktionary:Grease_pit/2017/May#Show-and-hide_templates_not_working_properly . We would appreciate if you could help us identify and solve what is causing the breakage. (This is apparently unrelated to https://phabricator.wikimedia.org/T164733 , despite the similar theme of collapsing beign broken?)
