🔖 Enhancement description

Increase the height of the "On this page" sidebar/table of contents or make it clear it's scrollable

🎤 Pitch

The "On this page" sidebar/table of contents has a max height of 600:

Because of this, not all headings show. For example, in the following screenshot, the last heading in the sidebar is "Automated certificate generation" but there's also "Using DNS challenge with DigitalOcean" under that.

This makes it look like the sidebar/table of contents is broken because it's missing the headings. In addition, there's no scrollbar so there's no indication that it's scrollable.
