I am using Autodesk.Viewing.ModelBuilder to add a clickable model in the Autodesk Viewer. While attempting to modify the shape of the added model, I used the changeGeometry method. Although the shape was successfully updated, I encountered an issue where the highlight indicating the selected state of the model does not disappear after clicking on it.

Code Example

 if (hit) {
                    let geom = new THREE.BufferGeometry().fromGeometry(
                        new THREE.BoxGeometry(10, 10, 60)
                    );
                    const material = new THREE.MeshBasicMaterial({
                        color: 0xff0000,   
                        transparent: true,
                        opacity: 0.5
                    });                        
                    const pillarMesh = new THREE.Mesh(geom, material);
                    pillarMesh.matrix = new THREE.Matrix4()pose(
                        new THREE.Vector3(hit.point.x, hit.point.y, hit.point.z),
                        new THREE.Quaternion(0, 0, 0, 1),
                        new THREE.Vector3(1, 1, 1)
                    );
                    
                    //model add
                    await viewer3D.loadExtension('Autodesk.Viewing.SceneBuilder');
                    const ext = viewer3D.getExtension('Autodesk.Viewing.SceneBuilder');
                    const modelBuilder = await ext.addNewModel({
                        conserveMemory: false, 
                        modelNameOverride: 'My Model Name' 
                    });
                    modelBuilder.addMesh(pillarMesh);

                    let newGeom = new THREE.BufferGeometry().fromGeometry(
                        new THREE.CylinderGeometry(5, 5, 60, 50)
                    );
                    console.log("changeGeometry", modelBuilder.changeGeometry(pillarMesh.geometry, newGeom));
}

Problem Description Once the geometry is changed, the highlight persists, even after attempting to deselect the model.

What I Have Tried Attempted to clear the selection using these methods:

viewer.clearSelection();
viewer.select([]);
viewer.toggleSelect(dbid, ModelBuilder.model);

None of these methods resolved the issue. The highlight remains.

Used changeFragmentGeometry instead: I replaced changeGeometry with changeFragmentGeometry to modify the geometry. However, the same issue persists, where the highlight does not disappear.

Expected Outcome I want to modify the geometry of the model dynamically and ensure that the selection state behaves correctly. The highlight should disappear when the selection is cleared or toggled off.
