setup(){
    const uploadInput = ref(null)
    const clickUpload = (e) => {
      if (uploadInput.value) {
        console.log(uploadInput.value) # 每次触发都打印了 2 次
        uploadInput.value.click()
      }
    }
    const fileChange = (e) => {
      console.log(e) # 第二次选择文件没有触发事件
    }
}

    
<template>
    <div class="container content">
        <div class="upload-box" @click="clickUpload">
        	<input type="file" class="hidden" accept="image/*" ref="uploadInput" @change="fileChange">
        </div>
    </div>
</template>

第二次选择文件为什么没有触发事件 ?
