Comment (by afercia):

 One more example of invalid HTML:

 https://core.trac.wordpress.org/browser/trunk/src/index.php?rev=45649&marks=33-55#L32

 The passed string avoids to set the initial opening tag `<p>`, which is
 smart, but then forgets to not pass the last closing tag `</p>`. Actual
 result in the HTML: `</p></p>`.
