BUG - Report Scheduler no longer allows multiple recipients in e-mail field

When I attempt to schedule a report and add multiple e-mail addresses with a comma between them I cannot save, I get an error message "Invalid e-mail address". I have a number of reports scheduled from EAP1 and they have multiple e-mail addresses, it was only when I attempted to edit one that I found this bug. I also attempted to add a new report with multiple recipients and received the same error.
