Description:
------------
I built a script which I pull the html down from a url and then do some editing and output the source with ->saveHTML(); 

I noticed every now and again the code outputted was missing characters in misc spots. For example one of my <div> became a <di>. I noticed this through a diff.

I wanted to eliminate it being on my end of the code so I simply pulled out all the code and left just $doc->loadHTMLFile($url); and then simply output with $doc->saveHTML(); 

If do this and hit refresh, it would during random refreshes lose the character (every 10/15 refreshes). It was always characters in the same place in my code, but random when they would disappear.

Reproduce code:
---------------
$conn = $doc->loadHTMLFile('http://www.chrishan.org');
	
if($conn){
    echo "<textarea rows=40>";
    echo $doc->saveHTML();
    echo "</textarea>";
}

Expected result:
----------------
I expect it to output my sourcecode from my website. But every 10 to 15 refreshes it loses a couple misc characters from my source.
