  }
}

What did you do?

<template functional>
  <section
    :ref="data.ref"
    :class="[data.class, data.staticClass, props.name]"
    :style="[data.style, data.staticStyle]"
    v-bind="data.attrs"
    v-on="listeners">
    <div class="label">
      <template v-if="props.label">{{ props.label }}</template>
      <slot name="label" />
    </div>
    <div class="value">
      <template v-if="props.value">{{ props.value }}</template>
      <slot />
    </div>
  </section>
</template>

<script>
/* eslint-disable vue/no-unused-properties -- https://github.com/vuejs/eslint-plugin-vue/issues/1312 */

export default {
  props: {
    name: {
      type: String,
      required: false,
      default: null,
    },
    label: {
      type: String,
      required: false,
      default: null,
    },
    value: {
      type: String,
      required: false,
      default: null,
    },
  },
};
</script>

What did you expect to happen?
No error, since data, props and listeners are part of the functional component context: https://vuejs.org/v2/guide/render-function.html#Functional-Components

What actually happened?
