Ended up doing a patch, it feels less hacky than a regexp.

Q: Why should we patch given that the preset has specified { node: 'current' } in targets option?

Oh right, it's not necessary. It was my first attempt at fixing these tests, and since it reduced the number of failure I didn't realize it's not what caused them.

I couldn't figure out how to make these two tests pass, so I disabled them for now.

The main problem is that Vue's Babel presets directly calls getTargets(), so even if we specify the top-level targets option it's ignored.

The proper way to update this test would be to pass to Vue's Babel preset ie: 9 as targets, but I don't know how to modify its options.

Reading through https://cli.vuejs.org/config/#babel and the setup think we just create a config file at https://github.com/vuejs/vue-cli/blob/89af6c50c2e559487d5ac24071a1f8589f9c026b/packages/%40vue/cli-plugin-babel/__tests__/transpileDependencies.spec.js#L19, worked for me

  await project.write(
    "babel.config.js",
    `module.exports = { presets: [
      ["@vue/babel-preset-app", { targets: { ie: 9 } }]
    ]}`
  );

await project.write(
'vue.config.js',
`module.exports = { transpileDependencies: true }`
