:handyman, since you are the author of the regressor, bug 1919752, could you take a look? Also, could you set the severity field?

OK, not sure what's going on but I can no longer reproduce the behavior where clicking somewhere on the page while the scan is in progress makes the file upload not happen. So I think it's safe to ignore that.

This bug will happen for any multi-file case that requires interaction (so, any with a WARN result). I'm not completely clear on why we are getting the WARN response instead of getting the response to the WARN response that should be sent by ContentAnalysis.sys.mjs.

I can no longer reproduce this issue with Firefox 133.0a1 (2024-10-24). This may have been reproduced before because of the folder name (warn) but after bug 1915351 it seems that we are hitting bug 1927099. Closing this.
