Defining a typed array element to a value that, when converted to the typed
array element type, detaches the typed array's underlying buffer, should
throw a TypeError and not modify the typed array.

3. If Type(P) is String, then
a. Let numericIndex be ! CanonicalNumericIndexString(P).
b. If numericIndex is not undefined, then

x. If Desc has a [[Value]] field, then
1. Let value be Desc.[[Value]].
2. Return ? IntegerIndexedElementSet(O, numericIndex, value).

15. Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue).
16. Return true.
