equalling the step ID is not necessary - the check of the
previous frame's ID is sufficient - but it is a common case and
cheaper than checking the previous frame's ID.
NOTE: frame_id_eq will never report two invalid frame IDs as
being equal, so to get into this block, both the current and
previous frame must have valid frame IDs. */
