| // This is different from ScreenLockNotificationBlocker because: |
| // - ScreenLockNotificationBlocker only cares about lock status but ChromeOS |
| // needs to care about login-screen. |
| // - ScreenLockNotificationBlocker needs a timer to check the screen lock state |
| // periodically, but ash::ShellObserver gets the events directly in ChromeOS. |
| // - In ChromeOS, some system notifications are allowed to be shown as popups. |
