Incomplete TOC when nesting order is unexpected

[cmaas]

Source:

# A
[[toc]]
### B
## C
## D

Config:

includeLevel: [2,3]

Expected result:

<ul>
  <li>
    <ul>
      <li>B</li>
    </ul>
  </li>
  <li>C</li>
  <li>D</li>
</ul>

Actual result: Shows only heading level 3 and nothing else.

Why would anyone do this? Because personally, I think level 1 is useless in a TOC, because that is the page header. I use level 2+3 only. I also use level 3 to have a heading in some kind of info box. The markup is like this:

# Nice article
[[toc]]
Blabla
<div class="infobox">
### Did you know?
Blabla
</div>

## Headline after info box
