Markdown adds redundant empty lines to listings in lists

Question

Markdown seems to duplicate empty lines in listings that appear inside a list:

1. Single empty line is duplicated

   Single empty line below:
   
   Single empty line above.
   

2. Two empty lines display correctly

   Two empty lines below:
   
   
   Two empty lines above.
   

When not inside a list, this works:

Single empty line below:

Single empty line above.

Indeed, this is a "feature" of most Markdown implementations, and ours is no exception.
