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?
