 - List current dispatches selectionChanged on arrowUp/Down. Should we subclass List
 and change behavior to commit value only on ENTER, SPACE, or CTRL-UP?
 
-` List
-
-- Handle stage resize
-- Add type assist
 - Add typicalItem support for measuredSize (lower priority) 
-- Change button to stay down when dropdown is open (?)
