package.json entry points with rollup and @rollup/plugin-node-resolve

Question

I'm looking for some help with package.json entry points (i.e. with @rollup/plugin-node-resolve, with snowpack). For a package I'm importing (indirectly via RxDB), I'm having some issues and according to its maintainer, it's just not choosing the correct entry point:

the broadcast-channel module is a esm module that has a different export index for browsers. You bundler should not include the methods/node.js file with the promisify call

The entry point in question:

https://github.com/pubkey/broadcast-channel/blob/master/package.json#L11

The exports section from package.json^ looks like this -- my understanding is that if I can get rollup to choose the entries under "browser" then that would solve my problem:

"exports": {
    ".": {
      "node": {
        "import": "./dist/esnode/index.js",
        "default": "./dist/es5node/index.js"
      },
      "browser": {
        "import": "./dist/esbrowser/index.js",
        "default": "./dist/lib/index.es5.js"
      }
    },
    "./package.json": "./package.json"
  },

I've tried the following options but it has not helped:

nodeResolve({
    browser: true,
    mainFields: ['browser'],
    exportConditions: ['browser'],
})

Can anyone recommend some alternative config options to try?

Additional info, in case it helps: the same issue comes up when I use @snowpack/plugin-webpack
