Module not found: Error: Can't resolve '../../src/methods/node.js' when bundling rxdb

Hello and thanks for the great tooling !

I'm running into the following issue when trying to bundle an existing app with @snowpack/plugin-webpack:

./web_modules/rxdb.js
Module not found: Error: Can't resolve '../../src/methods/node.js' in '/Users/qpre/connected_physics/platform-web-stack/app/client-web/build/web_modules'

      as directory
        /Users/qpre/connected_physics/platform-web-stack/app/client-web/src/methods/node.js doesn't exist

I'm using the following snowpack config:

module.exports = {
  extends: '@snowpack/app-scripts-react',
  scripts: {
    'build:css': 'postcss',
  },
  plugins: ['@snowpack/plugin-webpack'],
};

Via snowpack build --polyfill-node.

It works fine when using dev mode so I guess it is web pack related but can't find anything fixable from my POV as it seems to have to do with the way imports are rewritten.

I was able to track (thanks google...) it to the following module: https://github.com/pubkey/broadcast-channel

it's package.json has the following field:

"browser": {
    "./src/methods/node.js": false,
    "./dist/es/methods/node.js": false,
    "./dist/lib/methods/node.js": false
  },

adding it to my own makes build works, but it seems hackish at best.
any idea how I can avoid such issues in the future ?
