Style only but it would be nicer to rename beacon-common.js as beacon-common.sub.js and remove the ?pipe=sub

Looking at beacon-common.js, the polling mechanism seems fine.
I would tend though to stop polling and raise an error after a long timeout like 5 seconds but I am not sure how WPT would like that change.
