List formatting breaks when there's an empty line separating them

Thanks for catching that. I hadn’t looked at source.
I hadn’t had my coffee yet - that’s my excuse and I’m sticking with it.

This works better, but is far from being a perfect work-around. i.e. horizontal rule

* item A1
* item A2
* item A3
-----
- item B1
- item B2
- item B3
  • item A1
  • item A2
  • item A3

  • item B1
  • item B2
  • item B3
