Interestingly that code is also making use of `getClippingPlaneInDataCoords()`, there is actually another issue with clipping planes [here](https://discourse.vtk.org/t/how-to-make-addclippingplane-match-vtkreslicecursorwidget/10641/9).

It would be interesting to see if you have the bug in VTK.js v22 (prior to the changes with clipping plane in data coords)
