The permissions to view the latest revision tab currently use
view latest revision, and
view any unpublished content permissions.
It makes sense to have that check for
view own unpublished content too.
However, this is somewhat problematic because the node module defines
view own unpublished content, while content moderation defines
view any unpublished content.
Add the check for
view own unpublished content.
Figure out how to reconcile the node module defining that permission.
