Two tests fail in infrastructure/ on Firefox under Py3:

Unexpected Results
------------------
/infrastructure/server/http2-websocket.sub.h2.any.html
  TIMEOUT WSS over h2 - Test timed out
  TIMEOUT /infrastructure/server/http2-websocket.sub.h2.any.html
/infrastructure/server/http2-websocket.sub.h2.any.worker.html
  TIMEOUT WSS over h2 - Test timed out
  TIMEOUT /infrastructure/server/http2-websocket.sub.h2.any.worker.html

Running one locally I see:

./wpt --py3 run --log-mach - --yes --metadata infrastructure/metadata/ --install-fonts --install-webdriver '--binary=~/firefox-nightly/firefox' firefox infrastructure/server/http2-websocket.sub.h2.any.html

@jgraham - I'm not really sure what's going on here; I assume some Py3 bug in the websocket-over-http2 code, but I don't know where to start digging in.

Test passes in Firefox on Py2.

Test fails instantly in Chrome on Py2 or Py3 due to http2-websocket.sub.h2.any.js:3 WebSocket connection to 'wss://web-platform.test:9000/echo' failed: Error during WebSocket handshake: net::ERR_INVALID_HTTP_RESPONSE, so I assume (?) Chrome just doesn't support this.

Thanks for fixing this @jgraham ! PTAL, this PR should be good to go now. The Azure Pipelines failure is unrelated.
