Site header covers the top half of the section H2 header text when auto scrolling

[YanisaHS]

When you use the link for a specific heading on a page (e.g., https://ubuntu.com/landscape/docs/install-landscape-client#heading--install-landscape-client-from-the-main-repository), the auto-scroll covers the top half of the text in the section heading (H2) with the main Header bar.

This affects all pages that I tested it on in the Landscape Docs (and likely other Ubuntu docs). The photo shows what the section heading (H2) looks like when you auto-scroll directly to it from the heading link.
