Steps to reproduce the problem:
1. Use the Chromium API to trigger a download
2. cut network connection

What is the expected behavior?
Receive an "updated" event with state "interrupted"

What went wrong?
Received a "done" event with state "completed"

Did this work before? N/A

I initially reported this against electron as https://github.com/electron/electron/issues/6943

This seems to depend on the OS, on Win10 I see the expected behavior while it fails on MacOS X or Win7.
