xeogl.stats doesn't update on deletion of components from a scene.

[Thornton-developer]

I am trying to optimize my OBJ model using MergeVertices API. while checking for the parameters(modified indices, positions, uvs, normals) using xeogl.stats, It does update the stats, but wrongly, or abruptly(example : normals =65.3333).

Please see the code below.
function loadObj(objFile) {
var scene = xeogl.getDefaultScene();
// scene.clear();
logJSON({});

var mesh;
xeogl.loadOBJGeometry(scene, objFile, function (geometry) {
    var position_indices=xeogl.math.mergeVertices(geometry.positions,geometry.normals,geometry.uv,geometry.indices);
    var geom=new xeogl.Geometry(scene,{
        id:geometry.id+"_",
        meta:geometry.meta,
        primitive:geometry.primitive,
        positions:position_indices.positions,
        normals:position_indices.normals,
        uv:position_indices.uv,
        colors:geometry.colors,
        indices:position_indices.indices,
        quantized:true,
        combined:true,
        edgeThreshold:geometry._edgeThreshold
      });
    
    // scene.components["_18_"].destroy();
    geometry= geom;
    mesh = new xeogl.Mesh({        
    geometry:geom
    });
   
    scene.on("tick", function () {
         stats = xeogl.stats;
        logJSON(stats);
    });
});

new xeogl.CameraControl();

}

function onModelChange(elem) {
let objURL = URL.createObjectURL(elem.files[0]);
loadObj(objURL);
}

function logJSON(json) {
// json.client.browser = json.client.browser.substring(0, 10) + "...";
document.getElementById("logs").innerHTML = JSON.stringify(json, null, 4);
}

Expected behavior
It should display updated values after removing the duplicate vertices(using MergeVertices API) but instead of reducing the values of parameters, xeogl.stats produces higher values(normals before were 200, after merge vertices API call xeogl.stats shows 65.333 ,which is wrong).
