* Implement missing gamepad slots, align to spec more - Fixes TODO's from initial gamepad implementation - Adds some missing spec steps * Only handle gamepad events when pref is enabled * Return empty list in getGamepads if document not active * ./mach fmt * Update getGamepads to return an array instead of GamepadList * Add spec link for [[exposed]] slot * Remove failing test expectations for not-fully-active * A few fixes - Change should_notify to has_gesture - Add spec links and TODO to navigator - Remove unneeded clone from GamepadList::list - Move gamepadconnected event firing into has_gesture block * Use queue_with_canceller for tasks and add expects * Explicitly check for gamepad user gesture * Move user gesture check into separate function * Change contains_user_gesture to be a gamepad function * mach fmt * Change axis/button threshold constants to be private to module
