Description

Description:

I've been tracking down memory leaks and I noticed one stemming from the fact that if you call el.setObject3D("mesh", mesh) and then el.removeObject3D("mesh"), then mesh.el still references the A-Frame element. so if mesh is pinned to memory, so is the entire aframe subtree.

Research direction

Start by tracing the setObject3D and removeObject3D entry points in A-Frame and inspect how the mesh's el reference is assigned and cleared. Reproduce the sequence from the issue, then verify that removing the object no longer retains the element or its subtree, using any existing object3D tests if available.
