2109	Content-Type header is dropped when HTTP2 is used( HTTP status 204 only)	ms2008vip@…		"When backend server returned HTTP status 204 with Content-Type header.

The Content-Type header is set and sent correctly when using HTTP1.1(over plain-text HTTP or over HTTPS).

However, when making a request using HTTP2 (over TLS), that header is not sent.

I can't see a reason for this and would guess that this is a bug in Nginx. Or am I missing something?"	defect	accepted	minor		nginx-core	1.18.x		http2		Linux KONG 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux	"nginx version: nginx/1.18.0
