Steps to reproduce the problem:
The are several initialised  members in default constructor of ConnectionStateOnSentPacket in net/quic/core/congestion_control/bandwidth_sampler.h

This minor problem was found by coverity.

What is the expected behavior?

What went wrong?
Not all fields are initialised, can be fixed by something like:
