Plotly and MathJax issue in Jupyter Notebooks

I created a Jupyter Notebook with an (offline) Plotly plot embedded. When downloaded as HTML and viewed in a browser, the LaTeX equation is not converted by MathJax about 50% of the time that the page is loaded. A demo is attached which when loaded will display the equation correctly about 50% of the time. Tried in Safari, FF and Chrome (Chrome seems a bit more reliable, but not 100%). Removing the Plotly loading code causes the equation to always load correctly, so it looks like there is some kind of conflict. When the equation is not displayed, I can see that jax.js and fontdata.js are not loaded.

Possibly related to plotly/plotly.py#515 ?

At any rate sounds like a plotly.py issue. If it's alright, I'll close this since there's nothing to be done about it in plotly.js (ploty.js uses mathjax when appropriate but does nothing to actually load mathjax) but definitely sounds like an issue appropriate for the python bug tracker.
