Thanks for the information.
We already works on it.

The stack encounters this issue because the INVITE (caused by add participant) 
doesn't contains the list of participants unlike a INVITE caused by a new group 
chat. I don't know if this behavior is correct ?

The stack sends REFER to invite missing participants of a restarted group chat. 
As it doesn't have the list at this time, it sends REFER with all known 
participants...
To correct, we will move this feature at the NOTIFY reception to be sure to 
have a complete list of participants.

Yes, it is preferable to check if there is missing participants based on NOTIFY 
requests.

This mechanism must be done in case of a restarted group chat. 

But I think it should not be applied to this use case because the client left 
voluntarily the conference. 
Why did the client kept a list of participants for this conference?
