Incorrect markdown rendering paragraphs in list items

[quarckster]

Consider this markdown:

- first

    paragraph 1

- second

    paragraph 2

If I parse and render it with Markdown renderer the result is different:

import marko
from marko.md_renderer import MarkdownRenderer

parser = marko.Markdown(renderer=MarkdownRenderer)
parsed = parser.parse("- first\n\n    paragraph 1\n\n- second\n\n    paragraph 2\n")
print(parser.render(parsed))

- first

  paragraph 1
- second

  paragraph 2

marko version is 2.1.2

We don't guarantee the formats and indentation stability in markdown renderer. But the final result should be the same if to convert the markdown to HTML.

The above two markdown documents render to the same HTML.
