// the developer's perspective, the error is uncaught.

// DOM node, and call the user-provided callback from inside an event handler
// for that fake event. If the callback throws, the error is "captured" using
// a global event handler. But because the error happens in a different
// event loop context, it does not interrupt the normal program flow.
