description: >
  Atomics.waitAsync returns a result object containing a string "not-equal" and async is false.
info: |
  Atomics.waitAsync( typedArray, index, value, timeout )

  1. Return DoWait(async, typedArray, index, value, timeout).

  DoWait ( mode, typedArray, index, value, timeout )

  ...
  13. Let promiseCapability be undefined.
  14. If mode is async, then
    a. Set promiseCapability to ! NewPromiseCapability(%Promise%).

  ...
  Perform ! CreateDataPropertyOrThrow(_resultObject_, *"async"*, *true*).
  Perform ! CreateDataPropertyOrThrow(_resultObject_, *"value"*, _promiseCapability_.[[Promise]]).
  Return _resultObject_.
