Note that this is not a new failure, but an occasional flake that has been happening since at least Dec 25:
https://ci.chromium.org/buildbot/chromium.chromiumos/linux-chromeos-rel/3788

https://ci.chromium.org/buildbot/chromium.chromiumos/linux-chromeos-rel/4100

rdevlin@ - You've been doing some recent work in extension_messages_apitest.cc.  Could you take a look at this, or pass it on to a more appropriate owner?

NativeBindings/MessagingApiTest.Messaging/0 is failing too.

[Extensions] De-flake MessagingApiTest.Messaging

MessagingApiTest.Messaging was flaky on CrOS, failing when comparing
the value of the tab in the expected senders. Specifically, the value
of the tab's height was different. Since the same test tab is used
throughout the test, and the test modifies the content of the tab, there
are a number of factors that could contribute to this. Additionally,
this test doesn't really *care* about the tab's height.

Instead, compare only the properties of the sender that we expect to
be equal. For the tab, only compare the URL and the ID, which should be
sufficient to uniquely identify the tab (at least, as much as before).

Bug:  798560

Will check on Friday to see if the flakes have stopped.
