Navigation area were merged as part of full site editing and the new navigation block. This functionality is experimental and not currently used in WordPress core, so should be removed. Props noisysocks, spacedmonkey, get_dave, zieladam. Fixes #54506. Built from https://develop.svn.wordpress.org/trunk@52272 git-svn-id: http://core.svn.wordpress.org/trunk@51864 1a063a9b-81f0-0310-95a4-ce76da25c4cd
