Further development and editing on CSSOM is starting to ramp up again with
the recent addition of new editor resources.  Your questions have been
noted.

My current thinking, on which I would like to hear from other commenters,
is that CSSStyleDeclaration.length should include all non-ignored shorthand
properties that are declared in the associated CSS declaration block; i.e.,
if CSSStyleDeclaration.cssText includes 5 non-ignored properties, of either
longhand or shorthand form, then length should be 5. This would apply to
both border:inherit (CSS2...) and border:initial (CSS3) if the appear in
cssText.

If someone feels otherwise, please say so.
