Can these LocalFrames be Members?

BTW, can the plugin detect these raw pointers in HashMaps, Vectors etc?

It might be possible, I forget if this is one of the maps we had problems moving
earlier to the heap.

The GC plugin detects raw&unsafe pointers from collection objects.

     HashMap<DocumentLoader*, String> m_loaderToIdentifier;
     bool m_enabled;
     bool m_viewportNotificationsEnabled;
 
     bool m_touchEmulationEnabled;
     bool m_originalTouchEnabled;
     bool m_originalDeviceSupportsMouse;
     bool m_originalDeviceSupportsTouch;
     int m_originalMaxTouchPoints;
 
     bool m_embedderScriptEnabled;
     bool m_reloading;
 
     OwnPtrWillBeMember<InspectorResourceContentLoader> m_inspectorResourceContentLoader;
 };
