solved Bear glTF model could not display

[cx20]

I tried to display the following model in Sketchfab with Babylon.js.

bear_on_balloons\scene.gltf

However, when trying to display with Babylon.js sandbox, an error was output to the console and it was not possible to display the glTF model. It seems there is a problem with animation processing.

The issue is that there is an animation with only one key frame and that's not currently working. I'll fix it ASAP.

This is fixed with PR: https://github.com/BabylonJS/Babylon.js/pull/3243
