vite-issue-ssr-vue-async

Allow me to introduce one of the weirdest bugs I've ever encountered.

In this super minimal Vue SSR project, there is a single Root.vue component, which defined an async component Async.vue. During dev, the async component is rendered during SSR as expected. However, after bundling the server entry with esbuild (to mimic the production project where I'm encountering this bug) and running preview, the async component doesn't render.

Note: Client hydration has not been implemented in this minimal example because it is not relevant.

Steps to Reproduce

1. Run npm run dev and go to http://localhost:3000.
   Note that the async component is rendered during SSR and sent to the browser. 👍
2. Run npm run preview-entry and go to http://localhost:3000 again.
   Note that the async component is rendered during SSR and sent to the browser. 🤙
3. Run npm run preview-bundle and go to http://localhost:3000 again.
   Note that the async component is not rendered. ⛔️
