Spec bug: Thenable module breaks assert

[o-]

At https://tc39.es/proposal-shadowrealm/#sec-export-getter-functions the 1. Assert: exports is a module namespace exotic object does not hold given a module that is also a thenable.

Repro:

export function then(resolve) {
  resolve(42);
}
const sr = new ShadowRealm();
// Use import.meta.url to import this file itself as a module.
sr.importValue(import.meta.url, 'any_export').catch(() => {});

If I understand correctly this ends up doing:

7. Perform HostLoadImportedModule(referrer, specifierString, EMPTY, innerCapability).
-> "then it must perform FinishLoadingImportedModule(referrer, moduleRequest, payload, result)"
->  a. Perform ContinueDynamicImport(payload, result).
-> ii. Perform ! Call(promiseCapability.[[Resolve]], undefined, « namespace »).

Which means the 42 in the above example will be passed to ExportGetter functions.
