Tidy deletes empty tags #669
Description
When running tidy with html containing empty tags, many empty tags are simply removed. For example i, span and li elements. This is a problem as many of these elements are in fact significant, as can be seen in my example.
My version string: "HTML Tidy for Linux version 5.4.0"
A minimal, verifiable example:
<!doctype html>
<html lang="en">
<head>
<link href="vendors/css/ionicons.min.css" rel="stylesheet"/>
</head>
<body>
<span class="ion-bug"></span>
</body>
</html>
$ cat test.html | tidy > test1.html
produces
<!DOCTYPE html>
<html lang="en">
<head>
<meta name="generator" content=
"HTML Tidy for HTML5 for Linux version 5.4.0">
<link href="vendors/css/ionicons.min.css" rel="stylesheet">
<title></title>
</head>
<body>
</body>
</html>
