Repro:
$ ninja -C out/gn ... blink_tests
$ third_party/WebKit/Tools/Scripts/run-webkit-tests -t gn -v --no-retry-failures --additional-drt-flag=--no-sandbox --additional-drt-flag=--site-per-process http/tests/navigation/cross-origin-fragment-navigation-is-async.html
The differences in console output are understood and expected. In theory, we could unify test output across modes by always silencing console messages (i.e. this is what we've done in https://crrev.com/2042043002 and https://crrev.com/2015713002), but this is undesirable for the test from repro steps, because this would limit test verification/coverage (some discussion about this happened in https://crrev.com/2057833002).
