Error bars not scaled correctly in logarithmic 3D plots

[jonmmease]

Plotly.js translation of plotly/plotly.py#1139 reported by @jdieg0

generating a Scatter plot with a logarithmic y axis and given error_y works fine whereas creating a similar plot with Scatter3d with error bars results in extremely large error bars. The proportions of the error bars in the 3D plot are correct if type='log' is omitted.

In scatter the error bars work as expected.

// ## Constants
var x = [0., 1., 2., 3., 4., 5., 6., 7., 8., 9.]
var y = x.map(function() {return 0})
var z = [1.e+00, 1.e+01, 1.e+02, 1.e+03, 1.e+04,
 1.e+05, 1.e+06, 1.e+07, 1.e+08, 1.e+09]

var error_z = [3.e-01, 3.e+00, 3.e+01, 3.e+02, 3.e+03, 
 3.e+04, 3.e+05, 3.e+06, 3.e+07, 3.e+08]

// ## Scatter 2D
var scatter = {
 'type': 'scatter',
 'error_y': {'array': error_z,
 'type': 'data',
 'visible': true
 },
 'x': x,
 'y': z
}

var layout = {'yaxis': {'type': 'log', 'title': 'z'},
 'xaxis': {'title': 'x'},
 'width': 800,
 'height': 800};

var data = [ scatter ];

// ## Plot scatter 2D
Plotly.newPlot('myDiv', data, layout);

In scatter3d the errors bars grow very large

var scatter3d = {
 'type': 'scatter3d',
 'error_z': {'array': error_z,
 'type': 'data',
 'visible': true
 },
 'x': x,
 'y': y,
 'z': z
}

var data3d = [ scatter3d ];
var layout3d = {'scene': {'zaxis': {'type': 'log'}},
 'width': 800,
 'height': 800};

// ## Plot scatter 3D
Plotly.newPlot('myDiv', data3d, layout3d);

Perhaps error_z.type='data' is not implemented?
