 [https://github.com/WordPress/wordpress-develop/pull/1998 PR 1998] covers
 the port oversight causing the tests to fail on the Gutenberg repo, it
 also adds some tests to for sites running on a port.

 KSES can't match opening to closing tags (and to do so would be a major
 refactor) so following a discussion on the PR, it was decided the empty
 `object` tag was the best solution available.

 As this only becomes an issue if a user with `unfiltered_html` tries to
 mess with the input, I'm happy enough with that.
