Thanks for filing, I'll check into it

I'm digging into this a bit. It's doing a cross-origin POST and seems to be failing the CORS check. It's not clear why yet-- the request headers for the OPTIONS request seem correct. I also tried changing the User-Agent header to mimic chrome and that didn't solve it, so it doesnt appear to be the host doing some UA sniffing.

Okay it's not clear to me where the error is emerging. I suspect this is a weird interaction with Electron and Chromium. Here are the things we need to test (in an Electron fiddle):

• Do cross-origin POST requests via fetch() work?
• Do POST requests to HTTP which involve file uploads work?
• Do cross-origin POST requests to HTTP which involve file uploads work?

If anybody wants to pick this issue up, those are the 3 tests in Electron Fiddle we need to start with.
