I encountered this bug a few minutes ago, and decided to bring it up here. It happens when both asking and answering a question.
Steps to reproduce
1. Create bulleted list with a couple/few items. I checked, the size of the list doesn't matter, whether it's one or seven items .
2. Post a piece of code, formatted with four spaces below the list
3. Observe code not being formatted
It was really frustrating as I was trying to answer a users question, and the code wasn't formatting. The solution was I had to type something after the list, but is that really required?
