In a Moodle wiki is there a way to double space a numeric list?

To clarify the question, in the default Moodle 1.7 Wiki (based on Erfurt Wiki), numeric lists seem to only work if they are single space. If you put a line between them, then they restart each list item with 1. This Knowledgebase wiki-like formatting has the same problem

Single space numeric list.

1. should be one.
2. should be two.
3. should be three.

Double space numeric list.

1. should be one.

1. should be two.

1. should be three.

In Moodle when creating numbered listed using the html editor just hitting return will give you a singled spaced numeric list. However, to get double spaced lists you need to hold down shift, hit return twice and then return again (sans the shift key).

1. should be one : return
2. should be two : return
3. should be three : shift-return shift-return return

1. should be four : shift-return shift-return return

1. should be five
