The orders of sending packages in Debug mode and Run mode are different.

[FrankHuy]

When I use the method request in hyper.http20.connection,it's finally leading to the block of method named endheaders.

When I was debugging the program, the order of packets is like the pic.Data packet is actually after WINDOW_UPDATE[1] packet.

But I just let them running without debug.It was running like the pic.The first data packet was sent before the WINDOW_UPDATE[1] packet.And it wasn't recognized to be HTTP2 protocol packet by Wireshark.

It's so wired!!Please help me!Thx!!
