Not a bug Users without edit conversation permission can edit.

Affected version

v2.2.8 Patch 1

Despite "Member" user group doesn't have permission to edit messages in conversations, they still can.
I've tested it by making a test account "GlossyBean" which has the default permission and confirmed it can edit other participants' messages freely.

I suggest you check the Permissions Analysis to find out where the permissions are causing this.
