extra-offset is a last-minute measure after all positioning and
collision avoidance has already been done.  So whenever the positioned
idea of \f is moved in order to avoid a collision due to new elements
appearing, the extra-offsetted actual \f moves along.  extra-offset is a
blind brute-force control.  It most reliably does what you ask of it,
but it does not notice when the given task/offset stops making sense.
