How do I merge scalar arrays into vector array if each component is loaded into separate block? `VX*iHat + VY*jHat + VZ*kHat` [expression from FAQ](https://discourse.paraview.org/t/how-do-i-use-three-different-arrays-as-components-of-one-vector-field/4637) does not produce any output and does not throw any errors in this case (expressions like `VX*iHat + 0*jHat + 0*kHat` or `VX*iHat + VX*jHat + 0*kHat` work just fine).
