QUIC (HTTP/3) connection does not work when using SOCKS5 proxy

Hello.
When using socks5 proxies, QUIC (HTTP/3) connections do not work, only HTTP2.
I check here https://quic.nginx.org/quic.html

Strange. QUIC is just an add-on over UDP, just like HTTP is over TCP.
And Socks5 supports TCP and UDP. In theory it should work.
