Qt3D Mesh not working with STL format

Qt3D Mesh doesn’t work with STL format. The following code shows that the status of Mesh is always Loading

    Mesh {
        id: testMesh
        source: ":/meshes/cube.stl"
        onStatusChanged: function(status) {
            console.log("Mesh status:", status)
        }
    } 

Attached example shows the issue, it’s a modified version of the Qt 3D, Simple QML Example. The cube.stl used in the example is taken from the geometryloaders auto test, I’m assuming it’s a valid .stl file that can be used as an example to reproduce the issue.
