Disabling grid position changing on right click

In this example when we click and hold right click we are able to change position of grid, is there any way to disable this and enabling orbital controls as on left click on right click as well?

Thanks in advance

The idea is to configure rotation for right mouse button, too.

controls.mouseButtons.RIGHT = THREE.MOUSE.ROTATE;
