:+1: Attach can stay living in the injectWorker method for setup before attaching (URL checking), but wondering if `pipe` could be used for this when we want to forward to a different event:
`on(pageReadyEvents, 'data', function({page}) { emit(page, 'ready', {page:page}) })`
to
`pipe({ target: pageReadyEvents, event: 'data' }, { target: page, event: 'ready' })`
