[BUG] Innacurate preview

If you move text around (drag&drop), the preview doesn't follow.

Repro steps :

1. write something down
2. move the text around
3. the preview isn't updated.

Also, I believe that we should be able to create a list with line breaks instead of paragraph breaks.

AKA

Title :' '' '

1. list item
2. list item

Instead of : Title :
' '
' '

1. line item
2. line item
