ParsedGenerateSideset creates error when called after FancyExtruderGenerator

[snschune]

Bug Description

Error

*** ERROR ***
Invalid shape function index i = 2

encountered when ParsedGenerateSideset is executed after FancyExtruderGenerator. The error does not occur if
MeshExtruderGenerator is used.

Steps to Reproduce

[Mesh]
  [file]
    type = CartesianMeshGenerator
    dim = 2
    dx = '1 1 1 1'
    dy = '1 1'
    subdomain_id = '1 2 3 4
                    1 2 3 4'
  []

  [extrude]
    type = FancyExtruderGenerator
    direction = '0 0 1'
    heights = '1 1 1'
    num_layers = '1 1 1'
    input = file
  []

  #[extrude]
  #  type = MeshExtruderGenerator
  #  extrusion_vector = '0 0 3'
  #  num_layers = 3
  #  input = file
  #[]

  [add_side]
    type = ParsedGenerateSideset
    combinatorial_geometry = '2 > 1'
    new_sideset_name = new_s
    included_subdomain_ids = 1
    included_neighbor_ids = 2
    input = extrude
  []
[]

Impact

There are workarounds, like writing the mesh to file, reloading it and adding sidesets.
