Vuejs Component extends not working in webpack production mode

I make a componentChild extends componentParent.

It is describe in https://vuejs.org/api/options-composition#extends

// componentParent.vue
<template>
    <div>componentParent</div>
</template>
<script setup>
defineOptions({
    name: 'componentParent'
})
defineProps({...})
defineEmits({...})
</script>

// componentChild.vue
<script>
import componentParent from './componentParent.vue';
export default {
    name: 'componentChild',
    extends: componentParent,
    setup(props, ctx) {
        return {
            ...componentParent.setup(props, ctx)
        }
    }
}
</script>

In “webpack development” mode, componentChild is rendered

But, in “webpack production” mode, componentChild is not rendered. In html there are no dom.

(If componentParent is made as a option api, Everything is ok)

How can I render componentChild in webpack production mode?
