How to prevent animations from auto-starting by SceneLoader

Questions
1

Why do animated GLBs auto-start their animations (loading via SceneLoader.LoadAssetContainer), and how can I prevent this? I see the Animations in the container, but no Animatables that I can use to stop the animations started by the loader.

You can configure the GLTF loader to NOT start animation:

BABYLON.SceneLoader.OnPluginActivatedObservable.add(function (loader) {
        if (loader.name === "gltf") {
            loader.animationStartMode = BABYLON.GLTFLoaderAnimationStartMode.NONE;
        }
    });

Got it, thank you!

And for those like myself working in Typescript:

( loader as GLTFFileLoader ).animationStartMode = GLTFLoaderAnimationStartMode.NONE;

In TypeScript, we get animationStartMode does not exist on type ISceneLoaderPlugin | ISceneLoaderPluginAsync. I hacked around it with: (<any>loader).animationStartMode = ....

Can you provide a repro in the typescript playground, also those options can now be passed in the load call instead.
