Subject: [quicwg/base-drafts] RTO verified behavior (#935)

While implementing loss recovery from the draft, found some more weird behavior. When we get ACK for 2 packets sent after RTO, and RTO is verified, it seems like the psuedo code suggests that we use the reordering threshold again, however if we don't find a lost packet we would set the early retransmission timer again. This seems a bit weird that we would need to use the early retransmit timer after the RTO is verified and we could remove all the unacked packets < largest_sent_before_rto instead. Is this behavior intentional?
