description: >
  Setting a typed array element to a value that, when converted to the typed
  array element type, detaches the typed array's underlying buffer, will return true.
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.
  ...

  9.4.5.11 IntegerIndexedElementSet ( O, index, value )

  Assert: O is an Integer-Indexed exotic object.
  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 false and ! IsValidIntegerIndex(O, index) is true, then
    Let offset be O.[[ByteOffset]].
    Let arrayTypeName be the String value of O.[[TypedArrayName]].
    Let elementSize be the Element Size value specified in Table 62 for arrayTypeName.
    Let indexedPosition be (ℝ(index) × elementSize) + offset.
    Let elementType be the Element Type value in Table 62 for arrayTypeName.
    Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue, true, Unordered).
  Return NormalCompletion(undefined).
