Reset view after ctrl-clicking a Panel

Using ctrl+LMB to collapse all panels except of the clicked one resulted
in an empty area if done from a view that is scrolled down to some
degree. Resetting the view makes this much better, although it still
doesn't work that well if the area is really small, but I don't think
it's worth over-complicating things here.
