plots in Jupyter notebooks exports to HTML do not show without internet connection

A Jupyter notebook exported to HTML produces the error message

Uncaught ReferenceError: require is not defined

in Chrome when there is no internet connection. The plot does not show, there is only blank space where it should be.

reproducable example:

import plotly.express as px
iris = px.data.iris()
px.scatter(iris, x="sepal_width", y="sepal_length", color="petal_length")

and after:

jupyter nbconvert --to html ...

Exporting the plot directly with fig.write(...) works fine, both online and offline.

Please see my answer in the forum https://community.plot.ly/t/html-export-from-jupyter-notebook-for-offline-viewing/32104/13 I had missed an important information about the lack of internet connection, Does

import plotly.io as pio
pio.renderers.default = "notebook"

work for you?
