Loose lists on GFM seem ignored

[luixxiul]

Describe the bug
It looks like loose lists on GFM seem ignored.

To Reproduce
Steps to reproduce the behavior:

1. Create a list whose items are separated by a single lines

   - Test 1
   
   - Test 2
   
   - Test 3
   

2. Run make markdown

3. These blank lines are removed from the result:

   - Test 1
   - Test 2
   - Test 3
   

Expected behavior

These blank lines should not be removed.

Environment (please complete the following information):

• OS: Debian

Additional context
I confirmed that make html generated a loose list by wrapping list items with <p> tags:

<ul class="simple">
<li><p>Test 1</p></li>
<li><p>Test 2</p></li>
<li><p>Test 3</p></li>
</ul>
