Problem of the fun dictionary value being overwritten

Description of Issue

Problem of automatic overwritting the set value to the dictionary, when using reactor to post an event on a queue.

Setup

(Please provide relevant configs and/or SLS files (Be sure to remove sensitive info).)
reactor.conf

reactor:
  - 'salt/beacon/*/iptables/exceeded':
    - salt://reactors/schedule_queue.sls

schedule_queue.sls

{%- set split_tag = tag.split('/') -%}
{%- set orch_fun = split_tag[-2::1]|join('.') -%}
{%- set queue = split_tag[-2::1]|join('_') -%}
invoke_queue_scheduler:
  runner.queue.insert_runner:
    - fun: state.orchestrate
    - kwargs:
        mods: orch.{{ orch_fun }}
        pillar:
          id: {{ data['id'] }}
    - queue: {{ queue }}
    - backend: pgjsonb

Steps to Reproduce Issue

1. Configure schedule_queue.sls on reactors folder
2. Configure the reactor.conf
3. Trigger the reactor from a minion with the following code:

salt-call event.send tag='salt/beacon/*/iptables/exceeded'

(Include debug logs if possible and relevant.)
The salt renders and uses the correct information

Versions Report

(Provided by running salt --versions-report. Please also mention any differences in master/minion versions.)

[root@salt-master /]# salt --version                                                   │[DEBUG   ] SaltReqTimeoutError, retrying. (1/3)         │1 bash

Start with the reactor configuration in reactor.conf and schedule_queue.sls, then trace runner.queue.insert_runner and the pgjsonb backend using the supplied debug output. Compare the rendered runner arguments with the data stored by queue.list_items; done means the requested state.orchestrate function and arguments remain intact, with a regression test for this reactor path.
