Right navbar column skips the section clicked

[dylanh724]

Describe the bug

context
When I click a right column child header, it skips to the section above or below my cursor and awkwardly highlights the incorrect section:

expectation
When I click on a header anchor link on the right column nav, I expect it to go straight there and highlight the correctly selected link.

bug
Perhaps it has to do with smoothing scripts?

Reproduce the bug

Repro'd via your own release notes: Try clicking around the right nav (in Firefox desktop, at least) - it goes wild:

To add: The body anchors appropriately as expected; it's just the highlighted navbar item. Since the bug repro'd live on your site, it should be pretty easy to play with.

This can partially be repro'd on PyData:

However, this one only goes +1 up; it won't go +1 down. Still probably the same cause, though.
