Try this for giggles:
1 - Start Safari 4 (I think 3 may work, but 4 is what I have)
2 - Visit a web page
3 - Go to Window>Show Web Inspector
4 >> A window will open, or a new pane will appear showing data about the page. To the right is a column named Styles.
5 - Right Click over some of the text in Styles
6 >> A contextual menu will open up
7 - Choose the Inspect Element option
8 >> Another Inspector pane will open up.
9 - GoTo 5
You can keep on doing this until it gets silly. Safari is obviously using WebKit to create these lists, and is displaying them as a web page, and treating them as such.
