plotly.min.js overrides Promise

[zllovesuki]

When using plotly.js with Bluebird (global scope, without Bluebird.noConflict()), loading plotly.js seems to overrides the Promise.

Bluebird 3.4.6
Plotly.js 1.17.3
Chrome 53.0.2785.143 m (64-bit)

Try this:

1. Load Bluebird
2. Load Plotly.js
3. Promise.all([]).spread()

Expected Results:
3 returns a Promise

Actual Result:
Promise.all(..).spread(..) is not a function

maybe related to #955

Yep, same problem as #955

Importing plotly.js before Bluebird should solve the issue.

#2994 will add a handler for window.PlotlyConfig.MathJaxConfig as a way to configure MathJax "on load".

I'm thinking we could similarly add a handler e.g window.PlotlyConfig.noPromisePolyfill to skip over this line

plotly.js/src/core.js

Line 15 in a070a8d

require('es6-promise').polyfill();

on load.

This might be fixed by #5358.

This one we should explicitly test (manually, once, I don't see it as requiring a CI test) before closing.

Tested. It is fixed on master.
