Hello!

I am using HTML details tags in Jupyter notebooks; they are rendered fine in JupyterLab but rendered incorrectly on GitHub.

Please see an example here: [Rendering of `\<details\> HTML tag` on Github · GitHub](https://gist.github.com/dominiquesydow/55002f6f884e00a61382f850410ef703)

Does anyone know (a) why this happens on GitHub and (b) if there is a fix for this?

Thank you for your time.

Dominique
