Note that the rest of the TabStripTests appear to be well-behaved: https://test-results.appspot.com/dashboards/flakiness_dashboard.html#testType=chrome_public_test_apk&tests=org.chromium.chrome.browser.compositor.overlays.strip.TabStripTest


Sample failures:

https://build.chromium.org/p/chromium.android/builders/KitKat%20Tablet%20Tester/builds/5076
https://build.chromium.org/p/chromium.android/builders/Lollipop%20Tablet%20Tester/builds/4331
https://build.chromium.org/p/chromium.android/builders/Marshmallow%20Tablet%20Tester/builds/5018

in all three of the above, the failure appears to be the same:

I'm disabling the test for now.
