Notifiers was sent to outliner for redraw but outliner was out of sync
due to missing flag which is required for syncing.
This will correctly set the select/active outliner element flags with
the help of Base in `outliner_select_sync_from_object`. So correct active
tree element will be highlighted in `outliner_draw_highlights`
