when outer dom style change, How to prevent internal components Re-rendering?

[dragon9527]

<template>
  <div class="box" :style="boxStyle">
    <component v-for="item in props.parts" :ref="(el) => { getPartRef(el, item.animation) }" :is="item.component"
      :style="partStyle(item.position)">
    </component>
  </div>
</template>

when boxStyle change, getPartRef will call。
