If your screen is big enough, there isn't enough content below that tag that it automatically jumps to the bottom-most anchor: (e.g., https://slatedocs.github.io/slate/?python#errors). If your screen is small enough to have a scrollbar for that content, it works.
If there is not enough content to have a scrollbar, going to a specific anchor in a doc causes it to jump to the bottom-most anchor.
