Well, pages are most likely going to update the progress bar as often as 
we fire the event. So if we fire the event 50x/second then that's how 
often the progress bar will be updated.

Sure, some pages might do things like only update on every 10th event, 
but this seems like a complex future since then content might start 
relying on that implementations use a specific firing rate.
