Plotly cannot be loaded if Mathjax v3 is already loaded

Since MathJax v3, Mathjax.Hub does not exist anymore. This makes impossible to load PlotlyJS if Mathjax v3 has already been loaded. I get the following error:

TypeError: MathJax.Hub is undefined

I believe the error comes from these lines plotly.js:

module.exports = function() {
    if(typeof MathJax !== 'undefined') {
        var globalConfig = (window.PlotlyConfig || {}).MathJaxConfig !== 'local';

        if(globalConfig) {
            MathJax.Hub.Config({
                messageStyle: 'none',
                skipStartupTypeset: true,
                displayAlign: 'left',
                tex2jax: {
                    inlineMath: [['$', '$'], ['\\(', '\\)']]
                }
            });
            MathJax.Hub.Configured();
        }
    }
};

A check on MathJax version should probably be made here to use MathJax.Hub or not?

Here is a short example where plotly failed to be loaded: https://codepen.io/bthierry/pen/PoqwXzm

Many thanks!

MathJax v3 and plotly.js can be loaded together as long as the following is set before loading Plotly:

window.PlotlyConfig = {MathJaxConfig: 'local'}

Thanks for letting me know. Setting up a dev environment is a bit too much work for me, so I’m good on testing for now. I did give feedback though 😃
