Quota Clone not tracking unlimited quota

[Prakash Autade]

We are configuring 'Count quota' with 'Quota Clone Plugin'

Everything is working perfectly when we set limit in quota_rule(quota_rule
= *:bytes=500M).

In case of unlimited quota(quota_rule = *:bytes=0)
 - Count quota is updating values
* - Quota Clone plugin is not updating values in redis.*

We have configured dovecot as

mail_plugins = $mail_plugins quota quota_clone mail_log notify

mailbox_list_index = yes

plugin {
  quota = count:User quota
  quota_vsizes = yes
  quota_rule = *:bytes=0
  quota_clone_dict = redis:host=127.0.0.1:port=6379
}
