docusaurus: Updating to 3.2 breaks tailwind integration in production

Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I’m using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

Upgrading to 3.2 broke the tailwind styling, which I’ve integrated according to https://medium.com/@bargadyahmed/docusaurus-a-guide-to-seamless-integration-with-tailwind-css-dd202211caac

Here I’ve added the banner-preview with the custom tailwind integration flathub-infra/documentation@e0dc841 (#272)

It still works fine in dev, but breaks in prod or locally - if I do yarn build and then yarn serve. Unfortunatly the production errors are not helpful.

Basically https://docs.flathub.org/banner-preview/ should be styled. Like this:

Reproducible demo

https://github.com/flathub-infra/documentation

Steps to reproduce

1. Checkout repo
2. Run yarn
3. Run yarn build
4. Run yarn serve
5. Goto http://localhost:3000/banner-preview

Expected behavior

The page should be styled like in the above image

Actual behavior

The page isn’t styled, presumably because tailwind isn’t working, after upgrading to 3.2

Your environment

• Public source code: https://github.com/flathub-infra/documentation
• Public site URL: https://docs.flathub.org/
• Docusaurus version used: 3.2
• Environment name and version (e.g. Chrome 89, Node.js 16.4): Shouldn’t apply as it’s run on github
• Operating system and version (e.g. Ubuntu 20.04.2 LTS): Shouldn’t apply as it’s run on github

Self-service

• I’d be willing to fix this bug myself.
