Actually this bug exists for other objects that have their section properties decided by the object.
I have a footing beam that has a wall in the edge rebate. the section fill of the wall is controlled by a parameter, the fill of the beam by the default fill of the object. If I apply an operator to the object the fill in the wall changes to teh default fill.
