This flaky test/step was previously tracked in  issue 690663 .

+pmonette@, because the logs [1] show the following callstack (although I admit I don't really know if this callstack is directly related to the test failure - the logs are a bit confusing to me):

    chrome!base::debug::BreakDebugger+0xc
    ...
    chrome!logging::LogMessage::~LogMessage+0x46d
    chrome!base::subtle::RefCountedThreadSafeBase::AddRef+0x52
    chrome!base::internal::WeakPtrBase::WeakPtrBase+0x32
    chrome!base::WeakPtrFactory<content::AudioOutputAuthorizationHandler const >::GetWeakPtr+0x2b

Hmmm... this seems to be a dupe of  issue 840394 .  Let me try to figure out how to disable the test via content/test/gpu/gpu_tests/pixel_expectations.py and then dupe against the other bug.

Actually - fserb@, could you PTAL and 1) help decide if duping is desirable (the callstack in #c1 here seems different from the callstack reported in  issue 840394 ) and 2) mark the test as flaky in content/test/gpu/gpu_tests/pixel_expectations.py (I'd rather not do it myself, as I am not familiar with the desired format of the expectations + I am not sure if I should add a new expectations or reuse the one for  issue 840394 ).
