This is expected I think, because we respect CORS rules.

Couldn't that fail in a packaged app then? See the email discussion about on this for more detail.

I couldn't understand from those emails whether the issue in the failing tests is related to CORS or not.  We need more detailed bugs on file, but I thought CORS does work in packages apps?

Since createMediaElementSourceNode() can work in package app, I will file a new bug for rest of the fail test.

You can do CORS requests from a packaged app yes. The only problem is if the server only wants to share a CORS response with a particular packaged app since we don't have a good way to identify a packaged apps. I.e. packaged apps doesn't have good origins.

But for servers that are fine with sharing a file with anyone, CORS from packaged apps should work fine.
