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, should
throw a TypeError and not modify the typed array.
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. Return ? IntegerIndexedElementSet(O, numericIndex, V).
...
9.4.5.9 IntegerIndexedElementSet ( O, index, value )
...
15. Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue).
16. Return true.
