Description
Incorrect parsing of HTTP2 frame headers.
This happens when using Netty as the server, in the Java gRPC implementation server, in QtProtobuf, or with the `envoy` proxy server. The problem does not depend on the use of TLS and I can repeat it without encryption. It seems it does not correctly parse the HTTP2.0 protocol frame headers.
As result i can't use https://github.com/semlanik/qtprotobuf and my gRPC server on Java.Dependent issue in downstream projects https://github.com/qutebrowser/qutebrowser/issues/5588

qt.network.http2: connection error: SETTINGS invalid number of concurrent streams qt.network.http2: stream 1 finished with error: "SETTINGS invalid number of concurrent streams" QNetworkReply::ProtocolFailure "SETTINGS invalid number of concurrent streams"
I append code for reproduce
