If you're calling one of the other extensions, do that explicitly and not as an extension method.  See other `ValidationSummary()` overloads.

We're actually aiming to call the interface methods directly from all extensions but that's a nit at this point.  Might be better (temporarily) to stay consistent with those other overloads.  If you want to clean up the implementation of all `ValidationSummary()` overloads, more power to you but it's not necessary :smile_cat:
