package.json browsers field is not respected

[fireridlle]

Describe the bug

We are developing a package that is used by our community with vitejs.
In our package.json we have a field browser

  "browser": {
    "http2": false,
    "http": false,
    "https": false,
    "os": false,
    "util": false
  }

So all of these packages are NodeJs packages and we use them only if the code is running by NodeJS.
If code is running by browser, we don't want those packages to be at the final bundle as it increases bundle size.
Webpack respects this field, however, vitejs doesn't.
Is it possible to support this field or did I miss some additional configuration?

Even injected polyfill doesn't work well as it's kind of proxy and doesn't have named imports
original code

import { inspect } from 'util'

build code

import { inspect } from '/@id/__vite-browser-external'

an error

values.js?t=1617178902155:4 Uncaught SyntaxError: The requested module '/@id/__vite-browser-external' does not provide an export named 'inspect'

@fireridlle this should be fixed with the latest version of Vite, could you try with that one?
