This is interesting! While it’s not a Docusaurus bug, I recommend we document these weird behaviors down in a new FAQ page or something - maybe https://v2.docusaurus.io/docs/faq? I can think of more stuff to add into it (e.g. some prerendering-related issues).

@amilajack would you be interested in creating one?

Even if we don’t add it as an FAQ page on our site, we can create a Stack Overflow question so that the knowledge is shared and people can discover it easily.

I’d love to document this. I was wondering what the correct place to document this was. I was thinking of adding it to the “publishing with GitHub pages” section. What are your recommendations?
