ThisNote: the reason this issue was closed as "wonWon't fix" by [~Lucas C] but it's not explained why. Seeing his comment is the result of the forum proposal at https://jiraforum.xwiki.org/browset/XWIKIimplement-12824?focusedId=117831&page=com.atlassian.jira.plugin.system.issuetabpanels:commentcollapsing-tabpanel#comment-117831panels/13918 ( it seems the reason was that it was decided on the forum post that we don't want individual collapse/expand buttons for each panel).
