topic-navigation and topic-map appear in the DOM before the post stream, and are then rearranged with CSS grid. That means that, if they are entirely within the viewport, and does not have a fixed/sticky position, then they will be chosen as the browser's scroll anchor point.
We never want these elements to be used as the anchor, so we can set `overflow-anchor: none`.

Currently the tracking for clicked links are injected into the HTML in a span tag. This leads to the link counter value being highlighted when copying and pasting. Additionally, any means for using CSS to hide link counters result in a gap due to it occupying a specific width.
With this change, we make link counters appear in a data attribute on the link element and visually shown with CSS `::after` element.
Replaces the existing topic map with the experimental-topic-map made by @awesomerobot.
