loading.mobile/OLX_3g in performance_webview_test_suite failing on chromium.perf/Android Nexus5X WebView Perf

Issue description

Filed by sheriff-o-matic@appspot.gserviceaccount.com on behalf of charliea@chromium.org

loading.mobile/OLX_3g in performance_webview_test_suite failing on chromium.perf/Android Nexus5X WebView Perf

Builders failed on: 
- Android Nexus5X WebView Perf: 
  https://ci.chromium.org/p/chrome/builders/luci.chrome.ci/Android%20Nexus5X%20WebView%20Perf

It looks like this test got flaky somewhere between 615267 (good) and 616260 (bad). It was still failing before that, but the rate seemed to be much lower. Going to disable and kick off a bisect for now.

😿 Pinpoint job stopped with an error.
https://pinpoint-dot-chromeperf.appspot.com/job/149cf746940000

All of the runs failed. The most common error (20/20 runs) was:
TimeoutException: Timed out while waiting 180s for HasReachedQuiescence.

Hmmm, looks like the bisect is having even more problems with the story than the waterfall is. Going to kick this over to the benchmark owners for investigation. My guess is that we should be waiting for a specific element to appear onscreen instead of waiting for quiescence, which looks flaky.
