webpack polyfills did not work because useBuiltIns: 'entry' expects a explicit core-js import. Changed it to 'usage' which does not require these explicit imports and polyfills based on browserslist. As a result, the built index.js now went from 128kB to 192kB. Ref: https://babeljs.io/docs/en/babel-preset-env#usebuiltins Co-authored-by: zeripath <art27@cantab.net>
