Empty list items in table of contents when heading structure skips a level

[exprez135]

What version of Hugo are you using (hugo version)?

v0.68.3 on macOS via HomeBrew

Does this issue reproduce with the latest release?

Yes.

---

Whenever I enable the Table Of Contents in a situation without any endLevel specified in the site configuration:

Extra-Curriculars

Heading Four Here without Heading Three Before It

Technology

Heading Four Here without Heading Three Before It

The Table of Contents comes out looking like this:

I believe the expected behaviour would be for no extra bullet point to appear (or to appear with the H4).

If I add an H3:

Extra-Curriculars

Testing

Heading Four Here

Technology

Heading Four Here without Heading Three Before It

then:

Work-Around

If I manually set an endLevel, the problem disappears. It is only when one is not set that the problems occur.

Please re-open.

To reproduce:

git clone --single-branch -b hugo-github-issue-7128 https://github.com/jmooring/hugo-testing hugo-github-issue-7128
cd hugo-github-issue-7128
hugo server

Contrary to the original report, the following does not resolve the problem:

[markup.tableOfContents]
endLevel = 3
ordered = false
startLevel = 2
