This is clearly not a cover image for the article but a table in the middle of the article.

The <code> tag here is not removed, rendering the code blocks as inline <code>s instead of <pre> (as they're also rendered in the original page).

This is probably meant to be a subtitle.

Empty paragraph not removed

All of those shouldn't be <pre> blocks, but inline <code> blocks in the text below

There is an extra <br> at the top here not present in the original article.

This is part of the first paragraph, not the subtitle. Also, this breaks the actual first paragraph.

Those link doesn't work in IV, so they can be removed.

<code> tag removed from "squid-reverseproxy" text.
