+  A broken promise should reject the returned promise of
+  AsyncGenerator.prototype.return when the generator is completed.
+info: |
+  AsyncGenerator.prototype.return ( value )
+  ...
+  8. If state is either suspendedStart or completed, then
+    a. Set generator.[[AsyncGeneratorState]] to awaiting-return.
+    b. Perform ! AsyncGeneratorAwaitReturn(generator).
+  ...
+
+  AsyncGeneratorAwaitReturn ( generator )
+  ...
+  6. Let promise be Completion(PromiseResolve(%Promise%, completion.[[Value]])).
+  7. If promiseCompletion is an abrupt completion, then
+    a. Set generator.[[AsyncGeneratorState]] to completed.
+    b. Perform AsyncGeneratorCompleteStep(generator, promiseCompletion, true).
+    c. Perform AsyncGeneratorDrainQueue(generator).
+    d. Return unused.
+  8. Assert: promiseCompletion.[[Type]] is normal.
+  9. Let promise be promiseCompletion.[[Value]].
