GLTF importing fails to import animation

When importing GLTF model from:

https://sketchfab.com/3d-models/phoenix-king-d04bb96c5fb846c68b13754a8ece96a2

I get animation that does not fully match. There is only sequence that some feathers fly off the bird:

Steps to repro:
download the GLTF model from sketchfab and open it in Loader example.
