Godot Offline docs not self contained - Stylesheet required

I downloaded the offline docs from the link here: https://github.com/godotengine/godot-docs

Despite being offline, it's still trying to access two files:

This is a problem because I really am using them offline, so every time I click a link, Firefox spends a few seconds waiting on the CSS file at https://cdn.jsdelivr.net/npm/docsearch.js@2/dist/cdn/docsearch.min.css which of course it can't access.
