Standard Bundler is unable to handle circular dependencies properly.

[Protryon]

Given the modules:

// circular1.js
import circ2 from '/root/circular1_dep.js';
export var exportedResult = circ2 + 5;
var result = exportedResult;

//circular1_dep.js
export default 7;
import {exportedResult as circ1} from '/root/circular1.js';

The standard bundler does not provide the correct output of 12 for the value of result, as expected by the spec, or other implementations.

Module piercing does not have this issue.
