In order to land this I had to remove expectError: true from browser_webconsole_bug_595934_message_categories.js for a subtest involving a worker error event.  This was the only subtest using that, so if this behavior is important a replacement test should be found (I would suggest something with IndexedDB, where error events do bubble up to window.onerror IIRC)
