[BUG] Animation component tries to set weight on undefined

[AlexWarnes]

ISSUE
The Animation component on a loaded GLTF immediately throws the error Cannot set properties of undefined (setting 'weight')

POTENTIAL FIX
I can fix the error locally when updating Animation.svelte line 28 to check for action before assigning weight, like so:

if (action && action.weight) {
  action.weight = weight;
}

I'm new to SC and Three so apologies for wasting time if this is user error!
