Spawning animation is incorrect for some objects

**Description**
Objects should have a scaling animation when they are spawned, but it seems there's been a regression with the animation where some objects appear to animate their position instead.

**To Reproduce**
Steps to reproduce the behavior:
1. Spawn this book model: https://poly.google.com/view/0-_UGETLPsX
2. See that the spawn animation is incorrect compared to this model: https://poly.google.com/view/5rf3YuZfJAW

**Expected behavior**
Spawning should animate the model's scale consistently
