STR: 1. Load the attached file. 2. Press the button. => Notice there's an error in the console despite the fact that `preventDefault` is called in the JS handler for the "submit" event. Note that this doesn't happen in Chrome.
(Note: Bugzilla adds its own CSP header, so the results are a bit different when loaded from bugzilla's domain, but the error is still displayed)
