salt: Scheduled highstates from Windows-minions not returning to master

Description of Issue/Question

This issue was something we’ve run into in the past (#38371) and was fixed in #38923. On Linux, this works fine. The “workaround returner” I created and to used to workaround this in the past was no longer necessary.

However, we recently installed a few Windows machines with Salt and noticed that it was showing the very same behavior as with the previous issue:

• A salt-call state.highstate properly returns the salt/job/* event to the master
• A scheduled state.highstate does not return the salt/job/* event to the master

Setup

• Master on Ubuntu 16.04
• Minion on Windows Server 2016

Steps to Reproduce Issue

• Run Salt-minion on Windows
• Setup a schedule to do a highstate every X minutes
• Wait for the schedule to execute
• Listen to the eventsbus on the master salt-run state.event pretty=True
• Notice that only the minion/refresh/* and salt/auth events are being returned but no salt/job/* events for scheduled highstates
• Run a manual highstate salt-call state.highstate on the Windows minion
• Notice that the event is being returned to the master
