@marthacryan can you please check if this is connected with / fixed by changes in the release candidate?

@gvwilson Tried this out on master branch and it looks to still be present. I'm seeing this output when I run the nbconvert command: [NbConvertApp] Converting notebook test-notebook.ipynb to html /Users/marthacryan/micromamba/envs/plotly/share/jupyter/nbconvert/templates/base/display_priority.j2:32: UserWarning: Your element with mimetype(s) dict_keys(['application/vnd.plotly.v1+json']) is not able to be represented.
