Example in parallelism section needs to "queue a task" to handle the promise

[tidoust]

What is the issue with the HTML Standard?

The parallel queue example in the Parallelism section in HTML resolves/rejects a promise in parallel (or as part of a parallel queue) without first queuing a task: see steps 2.1 and 2.4 in both the "incorrect" and "correct" versions of the algorithm.

Via w3c/strudy#663 where I've started to look into automating detection of such hiccups in specs (although not in examples)
