What is the current behavior? See title

If the current behavior is a bug, please provide the steps to reproduce.

1. Go to https://mongoosejs.com/docs/deprecations.html
2. Mouse over a heading, e.g. "findAndModify()" or "The useNewUrlParser Option"
3. The anchor link icon appears ✔
4. As you move the mouse cursor toward the anchor link icon, it mouses out of the heading, which causes the anchor link icon to disappear:

What is the expected behavior? That it would stay long enough to click. In other words, probably that the anchor icon would be part of some shared element with the heading so that it's part of the same mouseover target area.

What are the versions of Node.js, Mongoose and MongoDB you are using? Note that "latest" is not a version.
