Scatter3D lines+markers with line color array error

[jonmmease]

For the scatter3d trace type, an error condition occurs when the line.color property is specified as a numeric array and markers is included in the mode flaglist.

Issue originally reported in of plotly/plotly.py#1093

CodePen: https://codepen.io/anon/pen/ZjjORB

x = [0, 0, 0]
y = [1, 1, 1]
z = [1, 2, 3]
c = [0, 1, 2]
var trace1 = {
 type: 'scatter3d',
 x: x,
 y: y,
 z: z,
 // mode: "lines",
 mode: "lines+markers",
 line: {
 color: c,
 showscale: true,
 width: 10
 }
}


var data = [ trace1 ];

var layout = {};

Plotly.newPlot('myDiv', data, layout);

When running example against plotly-latest.js I get the following JavaScript console error

TypeError: inputContainer is undefined
