There are still some leftovers where tracks were pushed "to avoid issues on boundaries when the tracks are located within Geant4". However, as no tracks are located in Geant4 anymore, but the navigation states are always cleanly converted from VecGeom to Geant4 and vice versa, none of these pushes are needed anymore.
Therefore, all pushes should be removed.
