I am referring to this issue https://github.com/MyNihongo/MudBlazor.Markdown/issues/117

Please refer to this sample:

var pipeline = new MarkdownPipelineBuilder().UseAdvancedExtensions().Build();

const string value =
@"<details>
  <summary markdown=""span"">Release 1.0.1</summary>

**New**
-  Error fixes.

</details>";

var parsedText = Markdown.Parse(value, pipeline);

The input is this HTML string, but Markdig returns 4 elements (<detals> + <summary>, some text in the middle, closing tag for </details>). I would expect it to return a single element which is just the HTML HtmlBlock, but maybe I am wrong in my assumption.

Could you please comment whether or not this behaviour is correct?
