Bundling dynamic import of entrypoint emits reference to non-existent _exports

[zachkirsch]

Minimal repro:

// src/a.js
export const A = 42;

// src/b.js
export const B = async () => (await import(".")).A

// src/index.js
export * from "./a"
export * from "./b"

esbuild command:

esbuild src/index.js --bundle --outfile=bundle.js --format=esm

Outputted bundle.js:

var __getOwnPropNames = Object.getOwnPropertyNames;
var __esm = (fn, res) => function __init() {
  return fn && (res = (0, fn[__getOwnPropNames(fn)[0]])(fn = 0)), res;
};

// src/a.js
var A;
var init_a = __esm({
  "src/a.js"() {
    A = 42;
  }
});

// src/b.js
var B;
var init_b = __esm({
  "src/b.js"() {
    B = async () => (await Promise.resolve().then(() => (init_src(), src_exports))).A;
  }
});

// src/index.js
var init_src = __esm({
  "src/index.js"() {
    init_a();
    init_b();
  }
});
init_src();
export {
  A,
  B
};

Bug: in the dynamic import, there's a reference to src_exports, but there's no src_exports defined!
