// synchronously. If you want to observe DOM tree mutation asynchronously see
// MutationObserver Web API.
// Note: if you only need to observe Document shutdown,
// ExecutionContextLifecycleObserver::ContextDestroyed provides this same
// functionality more efficiently (since it doesn't observe the other events).
//
// TODO(yosin): Following classes should be derived from this class to
// simplify Document class.
//  - DragCaret
//  - DocumentMarkerController
//  - EventHandler
//  - FrameCaret
//  - InputMethodController
//  - SelectionController
//  - Range set
