sendBeacon on Safari 13 seeing high failure rates
https://bugs.webkit.org/show_bug.cgi?id=204665
<rdar://problem/57522622>
Reviewed by Darin Adler.
Revert r245344 to try and reduce our failure rate for Beacon. This is the only change
to our Beacon implementation that I am aware we made in Safari 13. Using a lower priority
for Beacon makes it more likely that the Beacon load is still pending when the network
process exits, which would interrupt the Beacon.
Since we're trying to convince developers to move away from synchronous XHR and to using
the Beacon API intead, it is important that our Beacon API be as reliable as possible.
