On this page: https://meta.wikimedia.org/wiki/Talk:Terms_of_use?useskin=vector-2022 the "Quotations" section, which is hidden in a collapsed block generated by {{Collapse top}}/{{Collapse bottom}} templates, is always marked as active in the TOC, no matter where you scroll.
Even after clicking on a different section in the TOC, the page jumps there and the TOC momentarily marks the clicked section as active, but upon scrolling "Quotations" becomes active again (and the TOC scrolls to it, which hinders page navigation).
The issue disappears after uncollapsing the hidden content using the "Expand" button or by clicking on the "Quotations" section title in the TOC.
