From @AndrewArch

re the Resize text check, can we say anything about page that don't 'pinch-zoom' on mobile devices? Maybe record in backlog for next review?

Shawn agrees to consider adding this.

Note that most modern mobile browsers do not allow web developers to disable zoom nowadays – of course items can still overlap, so it would probably be a good idea to mention that pitfall.
