Looks pretty much like a rounding problem, if such 'circle' approximations are not displayed (however the 'limit' in Opera looks quite interesting - some rounding in the binary system?) Because elliptical arcs belong to the full profile and not to the tiny profile, the restriction to at most four fractional digits does not apply, therefore surely a bug, if browsers do not display it. On the other hand, to get really a circle one needs at least two elliptical arc segments. It is simple to avoid this rounding bug problem for the author by using two or three elliptical arcs to construct the circle (or in a tiny profile it works pretty well with three cubic path segments as well) - and in the elliptical arc case there is no need for a finite linear segment due to z - inital and final point of such a two or three segment circle can be exactly the same with a well defined circle as result.
