Incorrect global scope

Bug Report

• I would like to work on a fix!

Current behavior

node index.js
hasGlobal: fetch

Input Code

index.js

const { transformSync } = require("@babel/core");

transformSync(`export { fetch } from "node-fetch"`, {
  babelrc: false,
  configFile: false,
  plugins: [
    () => ({
      visitor: {
        Program(path) {
          if (path.scope.hasGlobal("fetch")) {
            console.log("hasGlobal: fetch");
          }
        },
      },
    }),
  ],
});

Expected behavior

node index.js

Hey @mo36924! We really appreciate you taking the time to report an issue. The collaborators on this project attempt to help as many people as possible, but we're a limited number of volunteers, so it's possible this won't be addressed swiftly.

This should be fixed by #12395, but we can add a test for the scope.

Was that the underlying problem for #9266 as well?

[nicolo-ribaudo]

Uh probably yes.
