Loading some glTF/glb animated models causes severe stuttering in Cesium, with the fps dropping close to 0.

### What happened?

Loading some glTF/glb animated models causes severe stuttering in Cesium, with the fps dropping close to 0. I have provided the model in the attachment, and it runs fine in desktop software such as Blender and 3D Viewer.

### Sandcastle example

_No response_

### Environment

Browser:
CesiumJS Version:
Operating System:

Start by loading the attached animated_drone.zip model in Cesium and profiling the frame rate during animation. The issue provides no Sandcastle example, reproduction steps, browser, version, or operating-system details, so first establish a reproducible case; done means the animated glTF/glb no longer drives the FPS close to zero.
