Thanks @convenient. There are actually several other related issues on this page. For example, headings with special characters aren't displaying properly in the On this page navigation box:

We either need to see if we can escape the special characters in markdown or remove the special characters from the headings, like we do in the MFTF guide. I have a feeling we may need to just remove them.

Also, this topic has a confusing mix of HTML and markdown. Pure markdown is preferable, but converting this topic would be tedious work.

At a minimum, we should fix the headings.

Fair. I was just correcting any bits and pieces I see while preparing for my certification. I don't have time to correct the further issues you have described so I'll just close this PR now, if anyone wants they can cherry-pick my commit across or redo the work or whatever 👍

We appreciate that fix @convenient! I'd like to keep this open so that someone on the doc team orr maybe a community maintainer can take it on.
