Some Draco format models are not displayed correctly

Bugs

I tried to display a Draco format glTF model in Babylon.js.
In Three.js, it is displayed correctly, but in Babylon.js, it seems that part is displayed in black.

It was displayed correctly when not using the Draco extension.

I remembered that there were cases where similar problems occurred with other libraries.

Thank you for your quick fix. I have confirmed that the model is displayed correctly with the latest version of Babylon.js v4.1.0 :tada:
