+   In its default configuration, the OptionsResolver treats all props. 
+   However, if more props are passed than the options defined in the OptionsResolver, an error will be prompted, indicating that one or more options are not defined. 
+   To avoid this, it is necessary to use the `ignoreUndefined()` method with `true`. See `ignore not defined options`_ for more info.

+      $resolver->setIgnoreUndefined(true);
+   
+   The major drawback of this configuration is that the OptionsResolver will remove every non-defined option when resolving data.
+   In order to maintain the props that have not been defined within the option resolver, it is necessary to combine the data from the hook with the result of the resolved data.

+      return $resolver->resolve($data) + $data;

 The data returned from ``preMount()`` will be used as the props for mounting.
