I looked at this in the VS debugger by loading the page in TestShell. The test passes but hits a DCHECK in timer.cc (this also seems to be the case from a quick look at the flakiness dashboard logs)

Here's the code:

void Timer::AbandonScheduledTask() {
  DCHECK(thread_id_ == 0 ||
         thread_id_ == static_cast<int>(PlatformThread::CurrentId()));
  if (scheduled_task_) {
    scheduled_task_->Abandon();
    scheduled_task_ = NULL;
  }
}

Here's the stack trace. I don't know what's going on but hopefully someone can shed some light.
