The inheritance issue was fixed by @saschanaz... But a new issue is present. Perhaps a convertCallbackInterface function should be created, or maybe just accept it in convertInterface?

src/widlprocess.ts:36:89 - error TS2345: Argument of type 'CallbackInterfaceType' is not assignable to parameter of type 'InterfaceType'.
  Types of property 'type' are incompatible.
    Type '"callback interface"' is not assignable to type '"interface"'.

36             browser["callback-interfaces"]!.interface[rootType.name] = convertInterface(rootType, commentMap);
                                                                                           ~~~~~~~~
