Back-office membership renewals don't display an on-screen notification
As part of CRM-16454, the membership renewal email code was moved from CRM_Member_Form_MembershipRenewal::submit()
to CRM_Member_Form_MembershipRenewal::postProcess()
. However, this code no longer generates a status message because of early returns.
Since the return values are ignored, it seems safe to ignore the early returns, which results in a status message comparable to a new membership.
