title: R Markdown: Empty line between list items
body: <p>I've encountered something in R Markdown, that is somewhat puzzling to me. When using ordered lists, I sometimes run into a case where no empty line is added between the list item. That happens after the second level of a list and going back to a first-level item. If the example below is "knitted" in Markdown, no empty line is added between the last subpoint of 2. and the 3. point. </p>
  
  <pre><code>1. This is a thing
  
  2. This is another thing
      + This is some subpoint thing
      + This, too, is something
  
  3. This thing should have an empty line above it. It does, when compiled as pdf, it doesn't in html.
  </code></pre>
  
  <p>I tried two spaces, \newline in various locations, but nothing worked correctly. I'm sure it's something easy that I just missed...</p>
  
  <p>Thanks y'all!</p>
