I'm not familiar with this test and it has a lot of magic numbers that aren't
validated in anyway. There should be comments here describing why 200 is better
than 10 and why 200 is right. I would also thing there is EXPECTS that 200 is
smaller than tab_view_bounds.

     gfx::Point above_content_point(
         tab_view_bounds.x() + tab_view_bounds.width() / 2,
         tab_view_bounds.y() - 2);
 
     // Start by moving the point just above the content.
     ui_controls::SendMouseMove(above_content_point.x(),
                                above_content_point.y());
 
     // Navigate to the test html page.
