offline "notebook" renderer with LaTeX requires an internet connection

[simon-mazenoux]

When using pio.renderers.default = "notebook" and exporting to HTML via nbconvert, the resulting HTML includes a MathJax import from a CDN:

"https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.5/MathJax.js?config=TeX-AMS-MML_SVG"

This behavior appears to contradict the documentation for the notebook interactive renderer, which suggests that all required assets should be self-contained: https://plotly.com/python/renderers/

Could you clarify whether this is expected behavior or a bug?

Oh I believe this is a bug! I have to check the behavior from plotly<6 but this should be a quick fix.

Additional context: Found a note on the intended behavior for including mathjax in offline mode:

plotly.py/plotly/offline/offline.py

Lines 522 to 524 in 1ec864b

	If a string that ends in '.js', a script tag is included that
	references the specified path. This approach can be used to point the
	resulting HTML file to an alternative CDN.
