Instead of the local position via el.getAttribute("position") consider the more general

let worldPosition=new THREE.Vector3();
worldPosition.copy(el.object3D.position);
el.object3D.parent.updateMatrixWorld();
el.object3D.parent.localToWorld(worldPosition)

Note though that it is more expensive to compute but allows to define the scene with parenting.
