test of poorly nested or complex youtube markup in a comment

[jywarren]

This demonstrates an issue with improperly parsed HTML markup in a comment, which can cut off the rest of a webpage by not closing the <iframe> tag.

It uses this text: https://gist.github.com/jywarren/dcee2c01d2dcfb969845d89374848fa1

Which gets displayed with the iframe tag like:

| <p>\<iframe width="560" height="315" src="https://www.youtube.com/embed/Kt\_MSMpxy7Y" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen\>\&lt;/iframe></p>

This should be solvable with https://stackoverflow.com/questions/9933333/sanitize-html-and-close-incomplete-tags

Nokogiri::HTML::DocumentFragment.parse(html).to_html
