An 'auto' value allows existing implementation to preserve their current 
behavior i.e. we wouldn't break the rendering of their content.

Doesn't prove there isn't a problem. Only that we haven't tested this as
Apple did, or with the same content.

The latter could explain the former; it also suggests that while there

No objection from me to testing what's out there. I think we should gather
that info and then come up with a solution vs. going for a UA stylesheet hack.

Dean, can you share URLs to some of the content you've seen breaking when
printed?
