lsquic has different action between gquic and iquic if set conn idle timeout 0

We set http_server with prog_settings->es_idle_to = 0 and prog_settings->es_idle_conn_to = 0, and then call http_client to send Q043 and h3-27 request to it.

Result：
Q043: Server destroy connection imediately after handshake completed.
h3-27: Server take client transport param idle timeout 30000ms, and send right response to http_client.

Does this expected? Or there are some bug? Thanks.

Start by reproducing the reported http_server and http_client scenario with prog_settings->es_idle_to and es_idle_conn_to set to 0 for Q043 and h3-27. Compare the connection behavior after the handshake and verify whether the differing idle-timeout handling is expected; done means the behavior is explained and any confirmed bug has a regression test.
