This is a problem raised in a Support Ticket.

If you insert a bodied macro (code, etc) into a bullet list, two additional paragraphs are added surrounding the macro. When the cursor is in the latter paragraph it is difficult to determine whether the cursor is still in the list or not. The only indication is the bullet button in the toolbar, which some of our users do not look at.

Also if your cursor is in that position, there is only one way to exist the list (pressing enter twice), which is not very discoverable.
