links from TOC not fully functional

## Is this a major issue that you cannot fix?

There are 101's with a table of content *including* a link to the corresponding header of a section. E.g., `Lists` and `Links` in the English version about [markdown](https://learnxinyminutes.com/docs/markdown/). In GitHub's processing, a click on the entry in the table of content promptly leads to the description in the body of the file.

This contrasts to the rendering on the other/external/possibly non-GitHub page (again the example of the English 101 about [markdown](https://learnxinyminutes.com/docs/markdown/). Here, a click on the entry in the table of contents does not lead to the corresponding section in the body of text.

Because both sites are accessed with the same version of Firefox web browser (102.6.0esr (64-bit), as currently provided by Linux Debian 12/bookworm, branch testing), I assume some relevant parameter for the non-GitHub page is adjusted differently.

With pandoc (version 3.0 from the [project's repository page](https://github.com/jgm/pandoc/tags)), I converted the markdown file into a self-sufficient .html file; here, the links from the TOC were functional. This is in additional evidence suggesting the rendering of the .html could be an issue here.

My requests to the moderators:

+ Can you replicate this observation?
+ If affirmative, please adjust the presentation of the non-GitHub page such that it equally yields functional links within the same page.
