This ended up being a content problem with the article in question, which is now fixed.

FYI: I switched the component for this to HelpHub since it pertains to one its articles, which are a custom post type with a handbook-like table of contents, though none of it utilizes the handbook plugin.

Details: The "Hosting" heading (anh3), below the first content heading "Performance factors" (an h2) had a manually assigned HTML anchor of "hosting" set. The regex for finding in-content headings essentially looks strictly for bare heading tags without accounting for attributes. So Hosting's manual attribute kept it from being detected, which threw off the inferred hierarchy of headings. Removing the HTML anchor fixed the issue. (The headings all get auto-assigned an anchor via the ToC code anyhow, so the manual assignment wasn't necessary.)
