The test is currently disabled in non-e10s. Running it in e10s, the screenshots the test produces are white, with the exception of the find bar itself, because the screenshots are taken in the parent process. The find bar showing/hiding promises are being interfered with by button transitions instead of the transition of the find bar itself, which is why this is starting to fail on infra when removing those transitions. I'm disabling the test given this series of issues. We have other, working tests for the find bar state itself, and we should fix this test to be more deterministic and actually take the screenshots in the content process.
Talked with Mike, not critical for 57.
