See XWIKI-23457 for an explanation of the UX regression this has caused.
The problem is at https://github.com/xwiki/xwiki-platform/blob/b0dbff028d803cbef22276adaff5720b9a57c02f/xwiki-platform-core/xwiki-platform-flamingo/xwiki-platform-flamingo-skin/xwiki-platform-flamingo-skin-resources/src/main/resources/flamingo/htmlheader.vm#L117-L121 since once users start entering content, they loose everything from meta.vm (as they won't include it in the majority of cases).
