I was editing http://stackoverflow.com/questions/2053029/ so the unordered list in the question was numbered to better correspond with the answer. I changed the first list item from a '-' to '1.' and in the preview block below, the rest of the list items changed to numbered items. However, when I saved my changes, only the first item was in a numbered list. In this case, the preview is probably incorrect, and should be changed to reflect what will actually be displayed in the question.

1. ichi - ni - san
Looks in the preview like:
But is rendered finally like:
- uno 2. dos 3. tres
