/**
 * @assertion void insertAll(int index, Iterable<E> iterable)
 * Inserts all objects of iterable at position [index] in the list.
 * This increases the length of the list by the length of iterable and shifts
 * all later objects towards the end of the list.
 * An error occurs if the index is less than 0 or greater than length. An
 * [UnsupportedError] occurs if the list is fixed-length.
 * @description Checks that [UnsupportedError] is thrown since [Float32x4List]
 * is a fixed-size list.
