if we allow longhand properties to be queried or set using their shorthand
form via getPropertyValue/setValue, then shorthands probably should be
enumerated by item();

there is also the issue of what happens when a current longhand is
re-designated in the future as a shorthand, and then subdivided into a new
set of longhands
