Describe the bug
I'm trying to write a GLTF2 exporter. So the output is somewhat out of specification and rough, but the animation in this file plays differently in Blender compared to Three.js.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
The animation should play like in Codium's three.js.

Version
Additional context
The main difference is three.js works and Blender import doesn't. So this import problem is blocking my use case of doing gltf2 exports to Blender.
Thanks for the fixed version! We can't guarantee that models failing validation will appear the same as in other engines, or at all, so that is appreciated.
