Spotted while implemented browsingContext.downloadEnd.

For test pages such as

data:text/html,<a href="https://not.a.real.url/whatever" download="file.txt">click

No download activity can be observed on the Downloads helper. Instead we perform a navigation. Nothing in the webprogress updates allows us to detect that this was from a download link either:

Links with download attribute might even trigger a navigation as long as the href is not in the same origin. Check the spec and file a spec issue.
