ClippingPlanes cannot be modified

### What happened?

There was no problem when setting the `ClippingPlanes` for 3D Tiles for the first time. However, an error occurred when modifying the `ClippingPlanes` again.

### Environment

Browser: Chrome
CesiumJS Version: 1.133
Operating System: Windows 11

Start with the linked Sandcastle example in Chrome and reproduce the error after the timer modifies the 3D Tiles ClippingPlanes value. Trace the 3D Tiles clipping-plane update path in CesiumJS and identify why the second modification fails. Done means repeated ClippingPlanes changes complete without an error in the stated environment.
