closes #9136 Changed the functionality in `make-absolute-urls.js` util to not convert the URL when starting which an `#`, as it indicates and internal link. The util is used inside of the `{{amp_content}}` helper and to render the RSS feed. I tested the changes with the most popular RSS reader 'Feedly' and it seems like these internal links get converted to absolute URL inside of Feedly automatically.
