Scrolling to the error message in Checkout - SCA (Elbrus) for SiteBuilder

Something has been bugging me since Reference Checkout days: if someone neglects to put in a security number for the CC and hits Continue it looks like nothing happens -- as the page does not scroll up to show the useful error message and now red-bordered input box.

I really needed to fix that for a client and did so this afternoon by adding the following line of code to an extended version of OrderWizard.Module.PaymentMethod.Creditcard.js  inside the error.errorCode === 'ERR_CHK_INCOMPLETE_SECURITY_NUMBER' if statement:

$(window).scrollTop($('.creditcard-section').offset().top);

Now if they don't input a security number, the page scrolls up and shows the error to them. I scroll up to the top of the cc info module as it looked better than just scrolling up to the security number input. That fixed this clients specific needs.
