Description:
------------
We've seen a variation in the behavior of end() when calling it on an ArrayObject between 7.3.26 and 7.4.23.

The test script returns the final element in the ArrayObject on PHP 7.3.26, but false on PHP 7.4.23.

I'm unclear as to why this behavior has changed as there are no documented changes to end() or ArrayObject behavior that I see in the PHP 7.3 to 7.4 migration guide.

Test script:
---------------
<?php                                                                                                                   
$arrayObject = new ArrayObject();                                                                                       
$arrayObject->append(new stdClass());                                                                                   
$arrayObject->append(new stdClass());                                                                                   
                                                                                                                        
var_dump(end($arrayObject)); 

Expected result:
----------------
I expect to have the final ArrayObject element returned by the call to end() on both PHP 7.3.x and 7.4.x.

Actual result:
--------------
On PHP 7.3.26, the final object within the ArrayObject is returned.

On PHP 7.4.23, false is returned.

This behavioral change has been introduced by commit
a5fa51afbb[1]; I'm not sure whether this was intended.

Ah, as of PHP 7.4.0, ArrayObject no longer supports end()[1],
etc.[2]  This is actually documented in the migration guide[3], but
may also need to be documented in the manual proper.  Furthermore,
the documentation of end(), etc., could be improved (it says
returns false for empty array).
