• HTML images just before a sublist should have a closing <img> tag added.
    • Otherwise, when rendered to Markdown again, the subsequent list items will be rendered as HTML.

  • A closing tag is also necessary if the image is followed by content on a new line.
    • Similar logic isn't necessary for images converted to Markdown.
  • It also isn't necessary if the next item is at the same level as the image...
  • ...or if the image has text just before it.
    • See this issue for details.
