This is a tricky function. I use it in my script for osm.org to navigate
between objects in a changesets, and sometimes it works unpredictably and moves
the scroll to the wrong place (or rather, sometimes it doesn't move the scroll
at all). Perhaps this is a problem with the current layout, but in any case, I
would be careful in expectations of it.

What is the point of doing this, then? Imagine, you are scrolling through
changesets, and finally an interesting cluster of edits appears in the area you
need, you move the cursor to them and the sidebar starts jumping. Then it turns
out that you need to load more changesets, and you move the cursor to the
sidebar again, enjoying its jumping.
Also, this is not the only solution. You can scroll with a delay. You can
scroll by alt + click by bbox. You can display by hover title with meta
information. You can show a popup. PR welcome :)

Now, viewing changesets on osm.org is a clean slate, so almost any change
doesn't make worse.
