  //       mechanism where we cannot abort the traversal of subordinate nodes
  //       and an imperfect parity between VTK and vtk-js (namely the lack of
  //       support in vtk-js for composite data structures). This logic should
  //       be removed when vtk-js support for composite data structures is in
  //       place.
