whether you need a linebreak
to add a newline
does the trailing space work (it seems to. TODO. document that)
Same list, linebreak?
Still a list item.
I'm surprised the preview acted differently, because it (IIRC) uses the same code path as normal post rendering.
EDIT: cannot reproduce linebreak problems. Can reproduce preview issues. Will investigate next week.
EDIT 2: Fixed bug with edit previews
But it is not the case in actual posts. This inconsistency should be resolved.
