"No WPT config file found" during local run-webkit-tests This is due to WPT config.json is not copied to correct place, but is tried to be retrieved even when running localhost_only=True scenarios. Also, the .json is parsed plenty of times during each r-w-t run, needlessly. Repro: run-webkit-tests --debug-rwt-logging --no-build --debug webgl
