geometery_colors, other properties not working when passed

On my installlations (and on binder right now), passing some initial settings for rendering do not work.

For example, passing geometry_colors=['g'] does not cause the Mesh example to initially render green.

```
viewer=view(geometries=mesh, geometry_colors=['g'] , ui_collapsed=True)
```

However, if you start the viewer and then display it and then set the colors as an np.array

```
viewer.geometry_colors = np.array([[0,1,0]], dtype=np.float32)
```

then the colors do change dynamically. But you can't set them to start (everything is always red)..

checking the viewer.get_state('geometry_colors') indicates that the front end did receive the correct data when passing geometry_colors to the view function, but it is not properly syncing what is rendered.
