Latest `thebe` loads CSS that breaks most paragraph CSS

Describe the problem

After updating this jb site (repo) for the first time since January, the paragraph breaks and bold fonts stopped showing up. They render correctly when I build locally (using the latest jb). I serve it with GitHub Pages & Actions.

For example, here’s how this page looks locally and on the web:

Locally

On the web

I’ve tried a few tweaks on the workflow file, which is essentially what’s in the docs.

1. Trigger a jb build with GitHub Action
2. Visit the site

Additional context

When I load/reload the page on the web, it shows the page with the correct paragraph break and bold font for a split second before removing them.

@lucasdekam yep - that is a step towards a more general improvement for the previous/next buttons. Here’s the final step for now:
