Virtual paths unexpectedly being rewritten

[marvinhagemeister]

Describe the bug

When a resolveId hook returns a namespaced path with a null byte in front, it will be rewritten regardless of that.

\0http://example.com/virtual.js -> \0https:/example.com/virtual.js

Reproduction

https://stackblitz.com/edit/vitejs-vite-gq5fry2q?file=vite.config.ts,src%2Fmain.js,index.html&terminal=dev

Steps to reproduce

Visit the minimal reproduction case, error occurs when launching vite and visiting the dev server.

  plugins: [
    {
      name: 'foo',
      resolveId(id) {
        if (id === 'virtual') {
          return `\0https://example.com/virtual.js`;
        }
      },
      load(id) {
        if (id === '\0https://example.com/virtual.js') {

Just checked with rollup and it doesn't rewrite the module id, so it's something in vite.
