Description:
------------
PHP 8.0.0a promoted the warning if passing invalid number of arrays to array_intersect(_key) was promoted to a fatal error. However, it seem that something changed in the version 8.0.0b4 since no error is produced.

Test script:
---------------
<?php

$arrayArray = [
    [1],[2]
];

array_intersect_key(...$arrayArray);// array_intersect

$arrayArray = [
    [1]
];

array_intersect_key(...$arrayArray);// array_intersect
