Export notebook to html, plots not rendered in html

Hi,

when I export a julia notebook .ipynb to html it does not export images from Plots.jl well and they are depicted as a svg html code not rendered. With PyPlot.jl the figures show as expected.

I don’t know if the problem is with Plots.jl or something within Jupyter-lab.

Using Julia 1.6.7,
[91a5bcdd] Plots v1.35.4

Any hints?
