Details

Right now they do, and the browser-chrome test harness depends on it: it sets window.onerror on the browser window and expects to see script errors from tabs and the like.

We could try to use a capturing listener here in the harness, but would need to watch out for error events from images and whatnot...
Error events from images didn't bubble.
Yes, which is why the chrome event handler isn't fired for them right now.  But if it were changed to a _capturing_ handler it would suddenly see those error events from images.
