### Actual Behavior

When reconstructed, the second last line did not have the right indentation.  When that was fixed, the 4th line did not have the right indentation.  These are both specific to 3+ drop cases with only lists.

### Expected Behavior

The markdown parse and back to markdown loop should not have any issues.
