Subject: [PATCH] wpLink: - Fix adding a link on pressing Enter. - Don't
 auto-focus the URL field after selecting a local link. - Don't auto-focus the
 URL field when opening on touch devices. Toggle focus/blur on it to close the
 onscreen keyboard so the modal is positioned properly. See #28897. Built from
