Annoyance: Hierarchical Browser

Ross,

Correctly scrolling the class selection into view in a newly-spawned 
tool has afaik *never* worked properly in the morphic versions of the 
tools -- neither in a spawned Hierarchy Browser, as you mention, nor 
in a full browser spawned via a "browse full".

All the other panes have their selections properly scrolled into view 
-- it seems that it's just the class-list pane that has a problem.

The problem does *not* occur at all in mvc.

Surely someone out there has some Labor-day cycles to throw at fixing 
this obscure bug!

Hint to anyone taking in interest in tracking this down: look in 
PluggableListMorph method #selectionIndex:.  For some reason, the 
scroll-selection-into-view branch is *never* taken for the class-list 
pane, though it kicks in perfectly for any other pane.
