Can't server-side render router with lazily loaded components

[kaathewisegit]

Describe the bug

I'm not sure if that's a bug or if I'm doing something wrong, but when I'm trying to use Route with components loaded via lazy, trying to render it with renderToStringAsync it returns an empty string.

https://github.com/kaathewisegit/solid-ssr-issue

Steps to Reproduce the Bug or Issue

1. npm install
2. Run npm run build:ssr or vite build --ssr src/entry-server --outDir dist/server/
3. run node dist/server/entry-server.js. It will return an empty string

Expected behavior

I expected it to return lazily loaded component. Replacing <Route path="/" component={lazy(() => import("./component"))} /> with an explicit import and <Route path="/" component={Component}/> makes it work correctly.
