"Reply all" can also CC to addresses that are also connected to Zoho, thereby disrupting ticket management

"Reply all" can also CC to addresses that are also connected to Zoho, thereby disrupting ticket management

What happened?
1. info@yourdomain.com and support@yourdomain.com also connected to Zoho as Email Channels. (Support@ is the default.)
2. customer (customer@example.com) wrote email to info@yourdomain.com and also CC it to support@yourdomain.com 
3. when agents sents answer with "Reply all" button, the Zoho sets:
      - To: customer@example.com 
      - CC: info@yourdomain.com 
4. And now, the ticket thread trashed with an unnecessary letter and the status is also reopened

It's inconvenient because
  1. agents have to manage the status again
  2. it's harder to find out what happened in the ticket view
  3. not to mention automations
  4. etc...
Possible solution:
If Zoho automatically filters out from CC, BCC those email addresses that are already attached as Email channels
