new scrollbar - Autoscrolling is not working with mouse drag selection

[Adi Roiban]

I am trying Natty and in applications like Nautilus or Gedit where the new scrollbars are enabled, when I try to select multiple icons or multiple lines, when the selection reached the windows margin, the windows viewport is not scrolled.

To reproduce this bug, try to open a long text file in Gedit. Then while holding the mouse left button move it down to select multiple lines. Go to the windows margin as when you would like to select more lines.
The view is not scrolled.
