description: Abrupt completion while getting value (Async generator Function declaration)

Async Generator Function Definitions
AsyncGeneratorDeclaration:

AsyncGeneratorBody }
YieldExpression: yield * AssignmentExpression
...
6. Repeat
a. If received.[[Type]] is normal, then
ii. Let innerResult be ? Invoke(iterator, "next",
« received.[[Value]] »).
iii. If generatorKind is async, then set innerResult to
? Await(innerResult).
...
vi. If done is true, then
1. Return ? IteratorValue(innerResult).
