        <pre>In the module system, the `Symbol.toStringTag` on the module namespace object should be resulting in the following holding true:

```
import * as m from './m.js';
Object.prototype.toString(m) === '[object Module]';
```

But the above is currently returning `[object Object]` instead.

This is a useful feature for detecting if a given object is a module namespace object, which will likely be necessary for interop use cases in future.</pre>
