Add scrollback to anchor links as the admin bar overlaps the heading

[garrett-eclipse]

Hello,

With anchor links on the HelpHub the admin bar gets in the way of the heading so it's unreadable.

For example;
​https://wordpress.org/support/article/cookies/#enable-cookies-in-your-browser

You'll find the heading hidden behind the wp-admin-bar.

Can we have a scrollback on anchors the height of the wp-admin-bar so the headings are readable.

Thanks

Anchor links leave headings overlapped by wp-admin-bar on wordpress.org
