The fb-comments bootloader image does not disappear

I have this simple HTML code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns:fb="http://ogp.me/ns/fb#" xmlns:og="http://ogp.me/ns#">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<div id="fb-root"></div>
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "http://connect.facebook.net/en_US/all.js#xfbml=1";

fjs.parentNode.insertBefore (js, fjs); } (document, script ',' facebook-jssdk '));      

The list of comments shows incomplete, and bootloader images never stop or disappear. What could happen

thank

I found that adding OpenGraph tags to the page fixes the problem. It seems that the tags are used by Facebook to link to comments on the page. I also saw that the problem occurs in local environments, but resolves when placed.
