// This is a regression test for a bug in `Task::IsCanceled()` (see
// https://crbug.com/1288882). Note that this function is only called on tasks
// inside the |delayed_work_queue|, and not for tasks in the
// |delayed_incoming_queue|. This is because a task posted through
// `PostCancelableDelayedTask()` is always valid while it is in the
// |delayed_incoming_queue|, since canceling it would remove it from the queue.
