When QUIC is discovering the link bandwidth, it sometimes increases the congestion window when there is not enough available data to use the existing congestion window.
In some cases, the congestion window can be too large for the path and cause packet losses if it is later fully utilized.
When the application is not generating enough data, or any streams with data are stream flow control limited.
None
Correctly check for data limitations before increasing congestion window.
