[cssom-view] finish removing 'instant' from scroll-behavior?

[tshinnic]

Currently under section "Changes From 17 December 2013" there is a note:

• The instant value of scroll-behavior was renamed to auto.

At "13. CSS properties" under "Smooth Scrolling: The scroll-behavior Property" it specifies Value: auto | smooth further saying "auto The scrolling box is scrolled in an instant fashion.". instant has been removed from here.

Yet there continue to be multiple references to 'instant' throughout the text, most confusingly at

• "IDL Index" where it specifies enum ScrollBehavior { "auto", "instant", "smooth" }; and at
• "Extensions to the Window Interface" which identically specifies enum ScrollBehavior { "auto", "instant", "smooth"};

There is a need to define the behavior "instant fashion" / "instant scroll" for descriptive purposes, but the residual mentions of instant, such as in "Terms defined by this specification" lend the feeling of transition, with the direction of such in doubt.

Are the continuing two instances in ScrollBehavior prescriptive or deceptive? Removing instant from both will cure the mentions in the index. A review of the description text may not be needed.
