⚠️ Broken since Chrome 65:

Block cross-origin <a download>

To avoid what is essentially a user-mediated cross-origin information leakage, Blink will now ignore the presence of the download attribute on anchor elements with cross origin attributes. Note that this applies to HTMLAnchorElement.download as well as to the element itself.
