The words "normative" and "should" are mutually exclusive. I agree that
browser should (and likely will, regardless of what we do) schedule these
callbacks to match the refresh rate of the display whenever possible, but
text in a specification that uses the word "should" instead of "must" is by
definition not a normative requirement. We can't always promise that the
callbacks will be invoked at the refresh rate of the display and so I feel
this is a quality of implementation issue.
