Safari's Reader Mode break the content

[AliSoftware]

When enabling the "Reader mode" in Safari, the content of the guides (any guides page that supports "Reader mode" anyway) is truncated and missing paragraphs (making the content inconsistent).

E.g. in the following capture, paragraphs are missing (see original page) at the beginning (starting from 2nd paragraph) and in other places of the content, and content stops prematurely, missing the end of the article.

This is because those code blocks contain a nested article node.

Also, some guides don't have the "Reader Mode" available, e.g. http://guides.cocoapods.org/using/getting-started.html (even though there is an article element in this page)

Also, what's with the < in front of each header/title?

The CSS content that adds it should be excluded from reader view.

I just realized that it's not just truncated in the end, it's even missing a lot of paragraphs in the middle. Like after the first paragraph, there is a whole block missing — from that 2nd paragraph to the first code block of the page's real content)
