// On Chrome OS, the clipboard is managed by aura instead of the underlying
// native platform (e.g. x11, ozone, etc).
// This class (1) monitors the aura clipboard for changes and notifies the
// |client_clipboard|, and (2) provides an interface to inject clipboard event
// into aura.
// The public API of this class can be called in any thread as internally it
// always posts the call to the |ui_task_runner|. On ChromeOS, that should
// be the UI thread of the browser process.
