I’m not sure if this is a bug, or an expected behavior, but, if you try to call super[“dynamicProperty”], given that superclass is dynamic, it will throw error telling you that the dynamic class \<name of dynamic class\> has no property “dynamicProperty”  
😕

BTW, the extending class is dynamic too.
