nginx - nginx TLSv1.3 冗余握手后会话票？

Question

所以我在 nginx 中使用 TLSv1.3，在测试期间curl我openssl看到了以下模式：

curl -v https://domain-using-tls2：

...
<request headers>
>
* TLSv1.2 (IN), TLS handshake, Newsession Ticket (4):
* Connection state changed (MAX_CONCURRENT_STREAMS == 128)!
< HTTP/2 200
<response headers>
...

curl -v https://domain-using-tls3：

...
<request headers>
>
* TLSv1.3 (IN), TLS handshake, Newsession Ticket (4):
* TLSv1.3 (IN), TLS handshake, Newsession Ticket (4):
* old SSL session ID is stale, removing
* Connection state changed (MAX_CONCURRENT_STREAMS == 128)!
< HTTP/2 200
<response headers>
...

并用 挖掘openssl s_client -connect domain-using-tls3:443，以下块出现两次（连续）具有不同的值：

...
Post-Handshake New Session Ticket arrived:

所以，我的问题是：TLSv1.3 协议中是否有一些东西强制 nginx 发送会话票两次，或者它是 nginx 的特殊内容？因为它看起来只是一些多余的东西，会被客户忽略......
