The runtime does not package the babel helpers while snackager uses runtime-transform

[mmomtchev]

Summary

My module exports a main and a module with the module using ES6 syntax which makes Babel to insert a couple of helpers:

yarn bundle @mmomtchev/[email protected] | ./node_modules/.bin/bunyan

file: /tmp/@mmomtchev/react-native-settings/web-bundle.js
--
externals: [
  "@babel/runtime/helpers/interopRequireDefault",
  "@babel/runtime/helpers/slicedToArray",
  "@react-navigation/native-stack",
  "react",
  "react-native"
]

What platform(s) does this occur on?

Web

SDK Version

v44.0.0

Reproducible demo or steps to reproduce from a blank project

I was able to narrow the problem to that fact that my module has type: "module" and I was able to reproduce the problem outside of snackager with raw webpack and presets: [ 'module:metro-react-native-babel-preset']
