"Expected result" is
'a' and TRUE
and not

Description:
------------
CachingIterator doesn't work if its innerIterator is an instance of
IteratorIterator.
The use-case provided here might seem strange as the IteratorIterator
is not necessary.
However, it would become necessary for a use case dealing with a
Traversable class such as PDOStatement, and the bug stays the same.
Additionnaly, we actually have to call next() manually but it should be
called internaly.
This leads to another bug which has already been reported at #46227
Reproduce code:
---------------
$it = new ArrayIterator(range('a','z');
$cache = new CachingIterator(new IteratorIterator($it));
$cache->next();
var_dump($cache->current());
var_dump($cache->hasNext());
Expected result:
----------------
1 and TRUE
Actual result:
--------------
NULL and FALSE
------------------------------------------------------------------------
