I guess Mac-wk1 has a platform-specific expectation file.

Reverted r243551 for reason:

Seems to have broken file uploads to SoundCloud

Steps to reproduce:
1 - Login to soundcloud
2 - "Upload"
3 - Pick an audio file and upload it

Results:
The progress bar for the upload never shows any progress (Hadn't gotten around to checking the JS console, probably should have)

Expected:
The process bar shows progress right away.

Notes: I found this and explored on device. Unclear if it affects desktop/sim the same

This is the part that broke SoundCloud. SoundCloud does not seem to send us a response and get expects progress events, we therefore cannot delay sending the progress events until we have a response.
