The most recent failure:
https://build.chromium.org/p/tryserver.chromium.chromiumos/builders/linux-chromeos-rel/builds/6874

The failure is:
../../chrome/browser/chromeos/system/tray_accessibility_browsertest.cc:1666: Failure

There's no clear regression range for this failure but the following patch recently changed this test and might have caused it:

It looks like jamescook is OOO this week. xiyuan, could you take a look?

emm, I am unable to repro locally...

Comment 2 by timloh@chromium.org, Nov 30 2017

Still flaky, e.g. https://build.chromium.org/p/tryserver.chromium.chromiumos/builders/linux-chromeos-rel/builds/13838. Going to disable the test for now.

Disable flaky test CheckMenuVisibilityOnDetailMenu

The test TrayAccessibilityTest.CheckMenuVisibilityOnDetailMenu is flaky,
so this CL disables it for now.

This is probably my fault.

cros: Enable TrayAccessibilityTest.CheckMenuVisibilityOnDetailMenu

The underlying accessibility code has been refactored recently and I
cannot reproduce flake locally. Also, the flakiness dashboard shows
that the other tests in the suite are not flaky anymore. I suspect
the issue is fixed.

Also add a RunLoop spin in one place that changes a pref that ash
may need to observe. I don't think that affects this test, but I
noticed it while investigating.

This test has run 60+ times in the last 20 hours on a variety of bots and I don't see any flake. Calling this fixed.
