Summary: Using LIBXML_HTML_NOIMPLIED on

This may be more of a documentation issue than a code issue. After encountering the same problem
recently, I found that the first element becomes the root element of the document. To offset this I
wrapped the html fragment in a root element, and I was able to work with it that way.
This is most likely due to our lack of understanding that the DOM Level 2 requires a document to
have a single documentElement, with children under it. I had to look that up to understand what I
was doing wrong.

Well, of course the behavior is reproducible -- only the expected
and actual behavior sections in the report are mixed up.

I am not able to reproduce this behavior, see
<http://3v4l.org/SFlNo>. Can you confirm?

Description:
------------
Using the LIBXML_HTML_NOIMPLIED predefined constant in the DomDocument class has unexpected results.
The nodeValue of any first DOMNodeList item always contains all the values of every node list item
in the collection only when the optional LIBXML_HTML_NOIMPLIED predefined constant is passed to the
loadHTML() method.
I am currently running:
- PHP Version 5.5.8
- libxml Version 2.9.1
Test script:
---------------
$html = '<h1>Foo</h1><h2>Bar</h2><p>lorem ipsum</p>';
$dom = new \DomDocument();
$dom->loadHTML($html, LIBXML_HTML_NOIMPLIED);
$nodes = $dom->getElementsByTagName('*');
echo $nodes->item(0)->tagName . ' -> ' . $nodes->item(0)->nodeValue .
'<br/>';
foreach ($nodes as $node) {
echo $node->tagName . ' -> ' . $node->nodeValue . '<br/>';
}
Expected result:
----------------
h1 -> FooBarlorem ipsum
h1 -> FooBarlorem ipsum
h2 -> Bar
p -> lorem ipsum
Actual result:
--------------
h1 -> Foo
h1 -> Foo
h2 -> Bar
p -> lorem ipsum
