See attached screenshots. IE does not display vertical scroll bar if the text item overflows; Firfox does not display scroll bar for most cases unless the total number of lines > certain threshold. The scroll bar does not seem help much when it is displayed (see the last screenshot in attached image). Webkit displays a scroll bar with > 0 pixel overflow. On Windows, real-world page that's affected: http://de.news.yahoo.com/wirtschaft.html, see text in right navigation strip saying "Wirtschaft: Alle Videos »" that has an unnecessary scrollbar. It happens this real-world page display fine on Mac because of the text font height difference between Win and Mac. Try attached html to see how the vertical scrollbar displays on mac. In this case, the scroll bar does not seem very helpful and the IE behavior looks better to me, think we should remove the scroll bar for list item. see bug for more info: https://bugs.webkit.org/show_bug.cgi?id=24434
