[...]
6. Let promiseCapability be NewPromiseCapability(C).
[...]
11. Let result be PerformPromiseRace(iteratorRecord, promiseCapability, C).
[...]
25.4.4.3.1 Runtime Semantics: PerformPromiseRace
1. Repeat
[...]
j. Let result be Invoke(nextPromise, "then",
«promiseCapability.[[Resolve]], promiseCapability.[[Reject]]»).
25.4.1.3.2 Promise Resolve Functions
[...]
8. Let then be Get(resolution, "then").
9. If then is an abrupt completion, then
[...]
10. Let thenAction be then.[[value]].
11. If IsCallable(thenAction) is false, then

12. Perform EnqueueJob ("PromiseJobs", PromiseResolveThenableJob,
