Thanks Christos,
I was aware of such things but haven't seen such a case.
Is there any way to "reproduce" this?
I believe it should be documented in the wiki.
Thanks,

Subject: Re: Splice certain SNIs which served by the same IP
Hi Ben,
When HTTP/2 is used, requests for two different domains may served using
the same TLS connection if both domains are served from the same remote
server and use the same TLS certificate.
There is a description here:
https://daniel.haxx.se/blog/2016/08/18/http2-connection-coalescing/
And a similar problem report here:
https://bugs.chromium.org/p/chromium/issues/detail?id=1176673
Regards,
Christos
