Code review comment for lp:~dyams/unity-2d/altf1-toggle-launcher-focus

Bug:
1. Have Launcher scrollable, i.e. has more icons than it can display at one time
2. With mouse, reveal launcher and scroll down to the bottom
3. Press Alt+F1

Expected Result:
Launcher repositions listview to top, highlights BFB button

Actual Result:
Launcher does not reposition, but BFB still highlighted.
