Are vnode-mounted vnode-update or vue:update lifehook event deprecated?

[jackchoumine]

I can not find them in docs.

another question:

I want to get dom width after updated ,but I get dom style by vnode-updated lifehook event, this style object value is empty string, why ?

</script setup>
function updated(VNode) {
  const tagsContainer = VNode.el.nextSibling.querySelector('.el-cascader__tags')
  console.log(tagsContainer.style, 'zqj log tagsContainer.style')
}
</script>
<template>
  <el-cascader
    v-model="selectedAdcd"
    :show-all-levels="props.showAllLevels"
    :props="innerCascaderProps"
    placeholder="选择地区"
    :clearable="props.clearable"
    v-bind="$attrs"
    @change="change"
    @vnode-mounted="mounted"
    @vnode-updated="updated" />
</template>

tagsContainer.style, is {key:''}

I can not get dom size.

const target = ref();

const rect = target.value.$el.getBoundingClientRect();

<MyComponent ref="target" />
