Example:

-> HEADERS(1)
- END_STREAM
+ END_HEADERS
:method: POST
:scheme: https
:authority: localhost:8443
:path: /
content-type: application/json
content-length: 58

Stream: RemainingSendFlowControlWindowIsEnough(58): 65535 > 58 = true
-> DATA(1)
+ END_STREAM
{58 bytes}

<- PUSH_PROMISE(1)
+ END_HEADERS
Promised Stream Id: 2
:authority: localhost:8443
:path: /

-> RST_STREAM(2)
Error code: REFUSED_STREAM

<- HEADERS(2)
- END_STREAM
+ END_HEADERS
:status: 400

<- DATA(2)
+ END_STREAM
{73 bytes}

Any thoughts on what's going on here?
