I hardcoded the values I'm trying to pass, and I got the regular progress messages to eventsource throughout the process (instead of until it was done). Something about POSTing this data without a header prevents these messages from sending...

The problem is that Fetch captures the progress messages. By its nature, the Fetch promise won't actually return anything until it is resolved. In short, EventSource is "flushing" the messages but Fetch is hoarding them.
The only thing this has to do with POST is that Fetch is the POSTer.
I've been experimenting and have not found an answer yet. I'm not sure there is one. There are responsibilities calling so I'm not sure when I'll have time to play with this again.
