Summary: AndroidScrollIntegrationTest.testFlingScroll is flaky on Lollipop Tabler Tester (was: AndroidScrollIntegrationTest.testFlingScroll is flaky.)
Don't think this is a this specifically testFlingScroll issue, checked the last builds after 4985 and it doesn't seem to occur there. When it fails, it is usually in conjunction with other tests.

general flakiness could be potentially related to  crbug.com/648573 
Status: Available (was: Untriaged)
Moving to "available" as per new bug triaging guidelines, up for grabs for any WebView team member.

This is still kind of flaky. see flakiness dashboard https://test-results.appspot.com/dashboards/flakiness_dashboard.html#showAllRuns=true&testType=webview_instrumentation_test_apk&tests=testFlingScroll, retry looks always succeed. Not only flaky on Lollipop.

Added this to go/webview-ideas.
