At the bottom of the following pages the "Next" links are not correctly linking to the next chapter in the TOC, instead they skip some of them:

• /doc/2.2/components/css_selector.html is linking to "DOM Crawler" instead of "Dependency Injection"
• /doc/2.2/components/routing/hostname_pattern.html is linking to "Security" instead of "Serializer"

Any idea how this can be fixed?
