no table of contents marker on sections with more than 110 lines

[v-au]

Describe the bug

context When a section contains more than 110 lines the table of contents marker is not displayed

expectation I expected the marker to jump to the corresponding section in the ToC as I move up and down the page.

bug But instead the marker disappears, and reappears when I reach a section with less than 110 lines. See the attached screen recording.

problem This is a problem for people using larger sections.

I see the same behavior at https://docs.software-univention.de/manual/latest/en/ip-config/radius.html#mac-authentication-bypass-with-computer-objects

I use SBT and customize the CSS to build the document. When you open the link in Firefox, the right sidebar should have 11.2.6.4 highlighted. In some cases it is, it some not. Scrolling up and down, marks the toc entry active or not.

I use SBT 1.1.0.

You can find the sources for the linked page above at https://raw.githubusercontent.com/univention/univention-corporate-server/5.0-6/doc/manual/ip-config/radius.rst
