Hmmm, turns out I was tricked! Android One Perf bot was online before running any tests. When tests were enabled it made it look like a regression, when it is just that the tests have always failed.

Still, there is a crash, but no possibility to bisect. Going to have to repro locally and see if I can symbolize crash.

Repro'ed locally. Copied some errors I saw below. Seems like its an OOM error. Maybe we should disable the infinite_scroll story on Android Ones?
