Description:
------------
DOMDocument::loadHTML() produces different results on Windows and Linux. Whitespace text nodes are ignored between non-inline elements on Linux but not on Windows.
The different behaviors are observed on the same PHP version (7.3.2) and very close libxml versions (2.9.3 on Linux and 2.9.8 on Windows).
Test script:
---------------
$doc = new DOMDocument();
$doc->loadHTML(
<<<HTML
<html>
<body>
<map>
<area />
</map>
<div>
<span />
</div>
</body>
</html>
HTML
);
var_dump(
$doc->getElementsByTagName('map')
->item(0)
->childNodes
->length
);
var_dump(
$doc->getElementsByTagName('div')
->item(0)
->childNodes
->length
);
Expected result:
----------------
int(1)
int(3)
Actual result:
--------------
int(3)
int(3)

Windows vs. Linux is irrelevant here; the behavior is different for different versions of libxml2; libxml2 2.9.10 on Linux also reports int(3) int(3) So this is an upstream issue, but not a PHP bug.
