Author does not see the scheduled take off-line / online when accepted by an admin / editor

When an author requests scheduled (de)publication, then after the request has been accepted, the document is not editable for the author, but no feedback at all is present. Admins and editors see a message on top when the document will be published/unpublished. See screenshots.

Certainly with in the future external workflow integrations, these feedback messages should be correct now already
