$refs chain, is that correct?

Question

Vue.js

Hello, please tell me if I get such a call in the component:

this.$refs.formCategory.$refs.dropzoneInput.removeAll(); //Очищаем dropzone при закрытии модального окна

Is it normal that I have a chain of refs ? , to simplify understanding, I will write:
The current component has a component

<form-category ref="formCategory" active="/categories_update"></form-category>

And inside <form-category>there is such a challenge

<dropzone-input v-model="category.image" title="Загрузить картинку" class="form__dropzone dropzone-elem" ref="dropzoneInput"></dropzone-input>

Thank you in advance for your response

No. Use vuex or event bus.
