Warning: the deletespace action validation step (after the space is removed) is forging a link to the deleted pages tab, see https://github.com/xwiki/xwiki-platform/blob/22eee6a3f51d8af14357255596ee78644c5a26a1/xwiki-platform-core/xwiki-platform-web/xwiki-platform-web-templates/src/main/resources/templates/deletedspace.vm#L35 This link needs to be adapted when moving to Live Data. See XWIKI-23169 for a comparable issue.
