Gltf-blender-io: Draco compression corrupt armature animations

[Nizaxx]

Describe the bug
Exporting gltf with draco compression on object with armature animation causes random jitter of verticies
Video: https://streamable.com/3ju4b (he should jump and move his fins up while jumping) from https://gltf.insimo.com/

To Reproduce
Steps to reproduce the behavior:

1. Download my project file
2. Select armature object and penguin object (penguin as first)
3. Export as gltf with those options
   
4. Import gltf file here https://gltf.insimo.com/

Expected behavior
Properly exported animation like without draco compression or error message that draco cant handle armature(?)

Screenshots
Corrupted animation:

Hi everyone,

I almost have the same problem with Blender 2.80 final version and Blender 2.81 beta with version 1.01 of glTF exporter. For me, with Draco Compression, the animation armature doesn't play when I drag and drop glb file on Sandbox Babylon.JS

Thank you very much for your work

Hi,
I just tested with version 2.82 Alpha - 416e66c7fe21 of Blender and it's good.
Great.
