Wrong Threshold on All Component

Description

Test added on VTK to test component modes fails on vtk-m. See vtk!10584 (merged)
The test fails when All component mode is set, and it gives one extra cell on vtk-m.

Steps to reproduce

It can be reproduced with the test from the MR and removing the condition in the CMake to build it when VTKM_OVERRIDE is enabled.

Otherwise:

  • Create a sphere with normals
  • Add a threshold filter on "Normals"
  • Use upper threshold function, and set it to 0.0
  • Disable All scalars
  • Set component mode to use All
  • Apply

On vtk-m you get 32 cells instead of 31 in VTK. The extra cell doesn't pass threshold's condition.
