cannot run example with x3d backend

[beew]

Hi, I am trying to run the example notebook https://github.com/enthought/mayavi/blob/master/examples/mayavi/mayavi_jupyter.ipynb

But running the cells

mlab.init_notebook(backend='x3d', local=True) 

mlab.figure()

Note the use of the figure here to create a new visualization.
s = mlab.test_points3d()
s

produces an error
