Overagressive about tree shaking modules used by other modules that re-export

[matthewp]

I think this can be recreated with:

one.js

import { foo } from './two';

window.foo = foo;

two.js

export { foo } from './three';
export { bar } from './other';

three.js

export { default } from './four';

four.js

module.exports = "works";

Looks like this was a case of using an older steal version. Closing as I don't think there's a bug here.
