Return true if key is a CanonicalNumericIndex and IsValidIntegerIndex(O, numericIndex) is false.

Assert: IsPropertyKey(P) is true.
Assert: O is an Integer-Indexed exotic object.
If Type(P) is String, then
Let numericIndex be ! CanonicalNumericIndexString(P).
If numericIndex is not undefined, then
If IsDetachedBuffer(O.[[ViewedArrayBuffer]]) is true, return true.
If ! IsValidIntegerIndex(O, numericIndex) is false, return true.
Return false.

IntegerIndexedElementGet ( O, index )

If ! IsValidIntegerIndex(O, index) is false, return undefined.
