I see; I didn't understand the notion of task. Ojan's original proposal included "onclick". Anne, are you arguing that we shouldn't include the event listeners in the options, and only allow them to be set after the constructor?

Do others agree with this? Or is the fact that showing is a queued task somehow implied already elsewhere in the spec? I'm just beginning to familiarize myself with spec-ese terms.
