@babel/polyfill does not get provided when you use vue ui and install babel as a plugin. After installing it manually it adds about 90kb to both my builds and does not build modern. @vue/cli-service, @vue/cli-plugin-babel and @vue/cli-plugin-eslint are updated to their latest version, imported the polyfill in the entry JS file and added the babel config file: module.exports = { presets: [ ['@vue/app', { useBuiltIns: 'entry', }] ] };

what am I missing here?

Modern mode still hangs for me @vue/cli 3.5.3. Please could someone confirm which version this fix should be present in, or what the version dependencies are?
