Selection triangle is hard to distinguish on Lion with standard (obtrusive) scrollbars

[jasonsanjose]

With a mouse plugged in (or "show scroll bars" set to "always"), the selection triangle overlaps the scroll bar track and thumb.

When over the track, there is barely enough contrast to see the triangle. When over the thumb, the triangle appears to take notch out of the right side of the thumb.

Hey Jason--it seems like the real problem is that when you plug the mouse in, Lion chooses to use light scrollbars instead of dark ones (probably because it bases it on the background-color of the app rather than the sidebar itself). I wonder if you could fix this by using the same ::webkit-scrollbar-* selectors that we're using for our fake unobtrusive scrollbars. LMK if you want me to take a look at this.

I worked out a fix where I just adjust the positioning of the triangle to account for the scrollbar width. I couldn't get the background color to change with webkit-scrollbar-track { background-color }. If you have any other tricks you want to try, go ahead and take the bug.

It looks like you need to do full scrollbar customization in order to change the track style. I think our options are:

1. Live with the ugly white track
2. Use our custom scrollbars everywhere, including Lion

We may be able to do #2 only if the scrollbars are persistant (either a mouse is plugged in or the user opted to have scrollbars be persistant), but I'm not sure if there is any JavaScript API to detect that.

NJ's a bit busy today. Assigning some sanity checking to Peter and Raymond before closing out.
