There is some inconsistency IMO about when the activity navigation shows up (the left/right buttons at the bottom of an activity)

The code relevant here is:

https://github.com/moodle/moodle/blob/d71532a7e03974aec22f018e3c9535a27bcbd56f/lib/outputrenderers.php#L1024-L1029

• Topics: uses_course_index() == true, pagelayout = 'incourse' -> returns nothing
• Social: uses_course_index() == false, pagelayout = 'incourse' -> return links

This seems really strange, since I would expect regardless if a page uses a course index, that it shows the activity navigation links.

Is there any reason for this check ?
