The biggest problem is that it inserts <ref /> at the very start of the page, on the same line as the infobox.

Cite => Manual => Basic Form => type some blanks => Insert
I don't think this is resolved since it's asking for Parsoid to drop empty unnamed references. It's still reproducible with the above steps.
The title is kind of misleading in that VE is sending these back without a body in data-mw, so it isn't really about the distinction in that patch (Sorry).
