body element removed

input:
```html
<html>
  <body style="color:white; background-color:black">
    <p>hello, world!</p>
  </body>
</html>
```

output:
```html
    <p>hello, world!</p>
```

is it possible to configure htmlpurifier to allow the body element?

edit: the original output I included was modified by my web browser, I got the actual purifier output with print debugging
