Call the [[DefineOwnProperty]] internal method of A with arguments "length", Property Descriptor
{[[Value]]: n + 1, [[Writable]: true, [[Enumerable]]: true, [[Configurable]]: true}, and true.
This is attempting to define an enumerable, configurable length property on an array, which will throw an exception trying to change the configurability of a non-configurable property.
