Nested lists - bug in numbering

[lofcz]

Describe the bug
If there is a ol nested in a ul's li, the first marker is incorrectly swapped.

Repro

<ul>
  <li>
    <h3>Text1</h3>
    <ol>
      <li>Text2</li>
    </ol>
    <ul>
      <li>Text3</li>
    </ul>
    <ol start="2">
      <li>Text4</li>
    </ol>
    <ul>
      <li>Text5</li>
      <li>Text6</li>
    </ul>
    <ol start="3">
      <li>Text7</li>
    </ol>
  </li>
</ul>

Should be:

Currently renders as:

Also, are nested lists of level 3+ not supported? Converting the same document with Pandoc handles them correctly:

Hi I was looking at your issue and would like to suggest you to set 2 options:
converter.ContinueNumbering = false

and for the heading, I'm not sure what you would really expect (just the style applied or having numbered heading?) but you can try also with converter.SupportsHeadingNumbering = false (sorry this is not yet published to a proper nuget package, still working on this release).

Let me know if that sounds okay to you.
