Additional recipients not recieving rejection emails

The following setting - Do you want to send an email notification to anyone outside of the approval flow when a Leave Request is approved or cancelled? located under - Organization > Team > Leave, Approvals & Calendars > Request Options 

Currently, if an employee submitted a leave request, this was approved by one of the managers, but then a few minutes later rejected, the emails defined as additional recipients do not seem to get any emails for requests that have been modified and the status is changed to rejected. The email notification is sent to the additional email addresses for approved and canceled requests, just not rejected.

It would be useful for additional recipients to be informed of leave/sickness request status changes via email too when the status is rejected.
