resident_on information in task at change watch shows in pool always the master

[Winteriver]

When watching changes with the xapi, all hosts of a pool receive all informations from every other host in that pool.

For example, when a snapshot is made at a slave of a Pool, the slave(s) and the master receive a task like:

{
allowed_operations: []
backtrace: "()"
created: "20190519T19:39:24Z"
current_operations: {}
error_info: []
finished: ""
name_description: ""
name_label: "VM.snapshot"
other_config: {}
progress: 1
resident_on: "OpaqueRef:36d4e8fd-7a8f-49c1-a9e8-4e38940a1302"
result: ""
status: "pending"
subtask_of: "OpaqueRef:NULL"
subtasks: []
type: "<none/>"
uuid: "65ace88c-b425-2b16-e6f8-1f7d407dcfbb"
}

Here - after my opinion - "resident_on" should display on which hosts that task has been started, like the documentation says:
http://xapi-project.github.io/xen-api/classes/task.html
"host ref resident_on - the host on which the task is running"

So "resident_on" should be the OpaqueRef of the slave, but it always shows the OpaqueRef of the master. This way it is not possible to assign the tasks to the right host.

The "resident_on" is working at the VMs and other stuff, but not with the tasks. Why? Is this a bug, or a feature? :D

Tested with: XCP-ng 7.6.0

It's a known "thing" of XAPI. Feel free to ask the question directly upstream: https://github.com/xapi-project/xen-api

Thanks very much for this information, its good to know. I made a copy of this question in the official xapi github:
xapi-project/xen-api#3870

If there are any news i will post it here.
