Chrome Version: ToT refs/heads/master@{#574880}

OS: Android 8.1.0.OPM4.171019.021

What steps will reproduce the problem?

ninja -C out/AndroidDebug -j2000 -l20 chrome_public_test_apk &&  out/AndroidDebug/bin/run_chrome_public_test_apk --test-filter "*NotificationPlatformBridgeTest#testShowNotificationWithoutIcon*" --local-output --no-retry

What is the expected result?

Test passes

What happens instead?

Test fails at 

l687:  
Assert.assertTrue(generatedIcon.sameAs(NotificationTestUtil.getLargeIconFromNotification(context, notification)))

But weirdly, this passes on the bots (even the Oreo bot)

https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=instrumentation&tests=org.chromium.chrome.browser.notifications.NotificationPlatformBridgeTest%23testShowNotificationWithoutIcon

Will flash to the latest public release of Oreo and see if that resolves things..
