Title: Fix bottom border on nested ul

Nested `ul` elements had a large bottom border. Most visible in a markdown doc such as:

```md
* Item 1
* Item 1.2
* Item 2
```

There would be a 16px border underneath "Item 1.2". This change sets the bottom border to 0 for nested `ul` elements, removing this gap.
