Description:
------------
When creating an IteratorIterator from a DomNodeList, it doesn't behave correctly.  The current
example behaves like the iterator-key is not reset properly when iterating although the value
returned is indeed the first entry of the iterator.


Test script:
---------------
$XML = <<< XML
<root>
  <item>1</item>
  <item>2</item>
  <item>3</item>
</root>
XML;

$dom = new DomDocument();
$dom->loadXml($XML);
$items = $dom->getElementsByTagName('item');

foreach ($items as $k => $item) {
	print "K: ".$k."  Item: ".$item->nodeName. " Value:
".$item->nodeValue. PHP_EOL;
}

print "----" . PHP_EOL;
$it = new IteratorIterator($items);
foreach ($it as $k => $item) {
	print "K: ".$k."  Item: ".$item->nodeName. " Value:
".$item->nodeValue. PHP_EOL;
}

Expected result:
----------------
K: 0  Item: item Value: 1
K: 1  Item: item Value: 2
K: 2  Item: item Value: 3
----
K: 0  Item: item Value: 1
K: 1  Item: item Value: 2
K: 2  Item: item Value: 3

Actual result:
--------------
K: 0  Item: item Value: 1
K: 1  Item: item Value: 2
K: 2  Item: item Value: 3
----
K: 3  Item: item Value: 1
