OH, very interesting. Thank you for this.
This makes me realize that my previous statement was perhaps misleading (or wrong depending on exactly what the original question was asking :-P ).
It seems like in GTK, the scrollbars appear ANY TIME you hover over the scrollbar areas. On Mac, the scrollbars only do anything special on hover if they are ALREADY showing for any other reason. So, for example, if you scroll a little and then quickly move the cursor over to the scrollbar area, then you will see the hover effect.
Another difference seems to be the the GTK scrollbars show up whenever you are moving the cursor around inside a scrollable box.
Very interesting!</pre>
