+description: throw() results in rejected promise when called on completed iterator
+info: |
+  AsyncGenerator.prototype.throw ( exception )
+  1. Let generator be the this value.
+  2. Let completion be Completion{[[Type]]: throw, [[Value]]: exception, [[Target]]: empty}.
+  3. Return ! AsyncGeneratorEnqueue(generator, completion).
+
+  AsyncGeneratorEnqueue ( generator, completion )
+  ...
+  8. If state is not "executing", then
+    a. Perform ! AsyncGeneratorResumeNext(generator).
+  ...
+
+  AsyncGeneratorResumeNext:
+  If completion.[[Type]] is throw, and generator.[[AsyncGeneratorState]] is
+  "completed", the resulting promise is rejected with the error.
