`Plotly.restyle` does not change style for scatter3d graphs

[dwoznicki]

Current behavior

Calling Plotly.restyle on a scatter3d chart does not apply any changes to the actual graph. See this codepen, where I attempt to change the opacity of the first trace. It's worth noting that the opacity does change in the legend.

Expected behavior

Plotly.restyle should change styling for scatter3d graphs.
