vite ssr - spaces in url leads to different req.pathname

[mkilpatrick]

Describe the bug

Making a request in SSR mode to http://localhost:5173/indextest/dangiel1 leads to the req.originalUrl looking like
/indextest/dangiel1
but making a request to http://localhost:5173/index%20test/dangiel1 (note the %20 space) leads to:
/@id/__x00__/index%20test/dangiel1

It's worth noting that my route handling is set up to handle a special root page:

  app.use(
    /^\/(.+)/,
    serverRenderRoute({ vite })
  );

  // Serve the index page at the root of the dev server.
  app.use(
    "/",
    indexPage()
  );

It doesn't reproduce with a simple setup. Please provide a reproduction.

Here's a reproduction - https://github.com/mkilpatrick/vite-ssr-react-base/tree/url-space. Start up the server and go to http://localhost:5173/about vs http://localhost:5173/about%20me.

It's related to inline modules and SSR.

[vite] Internal server error: Cannot read properties of undefined (reading '0')

/@id/__x00__/about%20me?html-proxy&index=0.js
No routes matched location "/@id/__x00__/about%20me?html-proxy&index=0.js"

It's happening in the vite:html-inline-proxy load code.

It seems there is an inconsistency of filePath.

vite/packages/vite/src/node/plugins/html.ts

Lines 62 to 66 in 937cecc

	// HTML Proxy Caches are stored by config -> filePath -> index
	export const htmlProxyMap = new WeakMap<
	ResolvedConfig,
	Map<string, Array<{ code: string; map?: SourceMapInput }>>
	>()

It reproduces with #9054 (comment), too.
