The summary is voluntarily vague because even if what happens is clearer, this is really what happened to me.

Steps To Reproduce:
- Download a file from a source that has HTTP headers set to always download.
- Go to chrome://downloads
- Click on the card to watch the video (more specifically, on the grey text that happened to be the url)

Expected result:
- Watch the video

Actual result:
- Enjoy downloading a copy of your file

Personal observations:
- it's a bit weird that we have three different hit targets on the card: the name will open the file, the "Show in folder" will open the folder and the URL will open the URL. Why the larger hit target actually using the internet on a "downloads" page? :(
- it's unclear to a user (like it was for me) that the grey URL is actually a click target for the URL. Usually, these are blue :(

Google-internal only:
- you can easily reproduce this by going to an internal bug and download a video, example b/69531488 and download the screenrecord
- when the file is downloaded, you clicking on the link will download a copy
