Comment (by sysrqb):

 I should also mention that because this download occurs speculatively, it
 is not bound to/associated with a firstPartyURI, so if the server requires
 a cookie (or the same originating-ip-address, or some other auth) obtained
 from another context/tab/domain-isolation, then this download will fail in
 a confusing way for the user.
