What happens if you suspend the app while transferring a file?

Hi everyone,
I’m using $cordovaFileTransfer to upload files in my app, and everything is working great. I had a question about suspending the app while an upload (or download?) is still in progress.

If I’m uploading a file, and while it’s uploading I suspend the app and go do something else on my phone, it appears to keep uploading (verified with xcode console output). I can’t seem to find documentation on this, how long will my upload continue running? Is there any sort of special handling I need to make sure the upload continues to run?
Thanks!
