Direct Uploads with AsT xhr status:0 intermittent

I’m getting the weirdest user error report using Direct Uploads and Active Storage. Extremely randomly (like 1% of the time) Active Storage returns the error “Error storing xyz file, status: 0” Looking at the Active Storage js code what this means is that the xhr.status is 0. Has anyone ever seen this? I can’t even reproduce it locally (they sent me a video so I know it’s legit).
