+ * The Idle Detection API can detect inactive users and locked screens.
+ * JShelter either removes the API (IdleDetector), or disables permission
+ * requests and returns user activity and unlocked screen (for previously
+ * granted permissions), or just always report user activity and unlocked
+ * screen.
+ *
+ * \bug JShelter does not block events, so the page is notified that
+ * something changed but it cannot read what changed.
