## What does this MR do?
Removes an overlap between the anchor icons on the readme and the sidebar on small screens by reducing the size and the padding of the icon.
## Are there points in the code the reviewer needs to double check?
Probably someone in the Design / UX team will need to review if the solution makes sense.

Issue #13334
