description: >
  Returns false if key has a numeric index and object has a detached
  buffer (honoring the Realm of the current execution context)
info: |
  9.4.5.5 [[Set]] ( P, V, Receiver)

  ...
  2. If Type(P) is String, then
    a. Let numericIndex be ! CanonicalNumericIndexString(P).
    b. If numericIndex is not undefined, then
      i. Perform ? IntegerIndexedElementSet(O, numericIndex, V).
      ii. Return true.
  ...

  IntegerIndexedElementSet ( O, index, value )

  Assert: O is an Integer-Indexed exotic object.
  Assert: Type(index) is Number.
  If O.[[ContentType]] is BigInt, let numValue be ? ToBigInt(value).
  Otherwise, let numValue be ? ToNumber(value).
  Let buffer be O.[[ViewedArrayBuffer]].
  If IsDetachedBuffer(buffer) is true, return false.
