Describe the bug

I have a library that defines:

{
  "name": "lib",
  "main": "./node.js",
  "module": "./node.mjs",
  "browser": "./browser.mjs",
  "exports": {
    "browser": "./browser.mjs",
    "import": "./node.mjs",
    "require": "./node.js"
  }
}

Contrary to the docs and expected behavior. Vite picks "module": "./node.mjs" and I get Node ESM printed. According to the docs, and Node.JS behavior, exports should be preferred and used when specified (P.S. Vite AFAIK doesn't use the browser main field).
