Anchor padding when navigating

[HugoFerrant]

When using the anchors in the doc (either by using the summary on the left, or accessing a url like this one : https://api-platform.com/docs/distribution/#a-bookshop-api), the desired title is not at the top. In reality, it's at top but the sticky menu is hiding it. Front-end/integration issue, but not my scope so can't really help more sorry !

tested on :
Firefox 85.0.2
Chrome 88.0.4324.182

In some cases it's not a big problem as it just hides the title, but there is some cases where it might hide important first paragraph
