Rule `import/no-unresolved` raise false positive when there is no `main` field in the `package.json`

What did you do? Please include the actual source code causing the issue, as well as the command that you used to run ESLint.

import GBAEmulator, { GbaContext } from 'react-gbajs'

Full code

./node_modules/.bin/eslint .

What did you expect to happen? Should raise no error. This package is present in the node_modules.

An important note: Since it's only for the browser, it has the field browser instead of main in its package.json (link). I made it following the NPM documentation. Despite that, I noticed that by adding the field main in its package.json, the error suppress - but it doesn't look correct.

What actually happened? Please copy-paste the actual, raw output from ESLint.
