- Platform / Device: At least Windows/Chrome (possibly all platforms)
- Reproducible Code Snippet or URL: https://pterko.github.io/aframe/memory_bug_demo/test.html
How to reproduce:
- Wait until page loads
- When page loads, take a memory snapshot

Research direction
Start with the reproducible test page at https://pterko.github.io/aframe/memory_bug_demo/test.html and trace the gltf-model lifecycle when its entity is removed from the DOM. Compare memory snapshots before loading, after loading, and after deletion; done means the model's memory is released after removal.
