// when it gets reset to undefined inside DynamicObject::ResetObject()

// Used to store the type of the prototype object in the prototype objects slots. Everything else (except ExternalType) are stored in this slot as Dictionary.
// Key in the Dictionary is combination of Type and TypeId and value is dynamicType object.
