By updating the PDF viewer mochitests to instead use the new support for re-dispatching general `EventBus` events to the DOM, as implemented in https://github.com/mozilla/pdf.js/pull/10019, this will allow (future) removal of the hard-coded DOM event dispatching currently present in the https://github.com/mozilla/pdf.js/blob/master/web/dom_events.js file.
