The site navigation pane on the left hand side displays in a staggered appearance (each successive line is indented from the previous one). This is different from the rendering of the site in Internet Explorer on Windows. Also check when clicking on one of the navigation links - the navigation pane changes when you go to a linked page, and the layout of the navigation pane on each linked page is also wrong.
Created attachment 7961 [details] Test case The bullets in the list is done with styled " ". Playing with different sizes (done in % and em) for the different styled properties shows that Safari sometimes indents the next list item, sometimes not. Zooming the page (cmd++/-) can also change the indentation.

Played around with this and WebKit's behaviour is consistent with Firefox. You will lose aligned indentation if you give the red floated bullets a big enough size as they will expand out of their own line and push the text below to one side. This is correct behaviour. Please re-open if you think there is still something to fix here!
