I don't think it's a CSS issue but more something related to how the chapters and sections are prepared upstream in rust, specifically in the file src/renderer/html_handlebars/helpers/toc.rs (in your example @frewsxcv chapters after 99 are put in a new "section" even if they are still chapters). I will try to propose a fix soon.
