  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 always return true.

  ...
  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.
