HTTP/3 with Firefox and forms

[Ryan Gould]

no, i am not seeing a thing in the logs.  i looked
in the php error logs and the nginx error logs, and
even the non-error logs.  the page returns immediately
after the POST is attempted.  it is not spending any
time debating or processing or round-tripping.

i can also verify the most recently added patch
did not fix the problem (not that it was supposed to): 
https://hg.nginx.org/nginx-quic/rev/dbe33ef9cd9a
