Hello,
if necessary, I will bulid a mwe, but maybe someone already has an idea without one.
Kernal: Julia 1.8 or 1.9
Problem: with julia 1.9 kernal, svg plots generated by Plots.jl (filename kwarg is set in plot call) are inlined in exported markdown files. I would expect them to be saved as files and included by something like  in the markdown file. With julia 1.8 kernel the behavior is as expected: The Plots are saved as svgs and included by  in the markdown file.
Second issue: a gif created by Plots.gif (…, filename, …) is saved under filename, but also inlined as base64 in the markdown file.
Thanks for your ideas
