--- Comment #2 from Chris Dumez <cdumez at apple.com> ---
Issue seems to come from the fact that target=_blank is used:
1. This triggers Safari's popup blocker. If you allow the popup later on, the filename is wrong because Safari does not know about the download attribute.
2. If popups are allowed, WebKit tries to *load* the blob instead of *downloading* it, thus the network error. This is due to a bug in our createNewWindow code path which I will fix.
