### Steps to reproduce

```

# Setup

git clone [email protected]:jayphelps/rollup-cjs-issue.git

cd rollup-cjs-issue

npm install

# Build

node build.mjs        # note the .mjs extension

# Run the results

node output.js

```

### The Error

```

link$1();

^

TypeError: link$1 is not a function

    at Object. (/Users/jayphelps/Projects/jayphelps/rollup-cjs-issue/output.js:3663:1)

    at Module._compile (node:internal/modules/cjs/loader:1083:30)

```

#### Notes

Likely the most notable place in the resulting bundle is here:

```js

var link = createCommonjsModule(function (module, exports) {

  exports.__esModule = true;

  exports.default = void 0;

  // ...code omitted for brevity here...

  var _default = Link;

  exports.default = _default;

});

var link$1 = link;

// TypeError: link$1 is not a function

link$1();

```

I tried to reproduce this with my own CJS file in `src/example.cjs` but rollup detects `exports.__esModule` and handles default imports of it correctly.
