Historical versions of sh ignore (or more precisely reset) the loop state when entering a shell function, so the continue doesn't have any effect. Posix doesn't say anything specific about it, but it doesn't call out a change from the historical behavior, so it came up reported as a bug. The discussion about the change took place on the dash mailing list, but the gmane.org archives are down right now so I can't give you a URL.
