A change to make a performance test longer has made it /much/ longer when run with an http/3 server.

Reproduce by grabbing D196841 and running:
./mach test --headless --use-http3-server dom/serviceworkers/test/performance/test_fetch.html

Log: https://drive.google.com/file/d/1JzcDkMpKKp3-rVIvoaoAgg8m_52IKHWm/view?usp=drive_link

Log was created with:
MOZ_LOG=nsHttp:5,nsSocketTransport:5,nsHostResolver:5 ./mach test --headless --use-http3-server dom/serviceworkers/test/performance/test_fetch.html

I arbitrarily cut the log off after 15k lines. It got up into the millions before I killed it.

Summary: test_fetch perf test takes a long time → test_fetch perf test takes a long time with http/3
