how to use rotateX in volume rendering

Could someone help to verify or acknowledge this issue.

The code to repeat is really simple, just a few lines of code, easy to read.

you can switch between createGenericRenderWindow and createFullScreenRenderWindow to check.

Unfortunately, on my local machine with vscode neither works, so I could not debug myself by comparing the difference step by step. It may need someone with deeper knowledge of vtk.js.

Thanks.
